Sort a multidimensional array by a column then by first level keys

Question

I've got the following structue of array, but I need sort by mark value and on duplicated need sort at last by array index:

this is my Array base $AsocContData[$s_list_100]:

array(5) {
    [01081] => Array(3){
        [id] => 2
        [Mark] => 420
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
    [00358] => Array(3){
        [id] => 6
        [Mark] => 500
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
    [00277] => Array(3){
        [id] => 3
        [Mark] => 400
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
    [00357] => Array(3){
        [id] => 1
        [Mark] => 500
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
}

What's the best way for order the array by sub-array and on duplicated use the Index array, incremental?

So the results look like this:

array(5) {
    [00277] => Array(3){
        [id] => 3
        [Mark] => 400
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
    [01081] => Array(3){
        [id] => 2
        [Mark] => 420
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
    [00357] => Array(3){
        [id] => 1
        [Mark] => 500
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
    [00358] => Array(3){
        [id] => 6
        [Mark] => 500
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
}

Update

I try to use this, but it does not have the desired scope with php 7.2:

usort($AsocContData[$s_list_100], function ($a, $b) {
    return $a['Prod_Mark'] <=> $b['Prod_Mark'];
});

this return and not sort for duplicates:

array(20) {
  [0]=>// remplace this first Index array with position and it is a fail.
  array(38) {
    
  }
}

Update

the base array is dynamic nested, and can have much more Array child nested.

You should probably use array_multisort()

array_multisort(
    array_column( $AsocContData[$s_list_100], 'Mark' ), // sort by the Mark sub-array value first
    SORT_ASC, // ascending
    SORT_NUMERIC, // treat data as numeric
    array_keys( $AsocContData[$s_list_100] ), // secondly, sort by the array indexes
    SORT_ASC, // ascending
    SORT_NUMERIC, // treat indexes as numeric
    $AsocContData[$s_list_100] // this array will be sorted in place and by reference
);

var_dump( $AsocContData[$s_list_100] );

Input:

$AsocContData[$s_list_100] = array(
    '01081' => Array(
        'id' => 2,
        'Mark' => 420,
        'lastUpdated' => '2010-03-17 15:44:12'
    ),
    '00358' => Array(
        'id' => 6,
        'Mark' => 500,
        'lastUpdated' => '2010-03-17 15:44:12'
    ),
    '00277' => Array(
        'id' => 3,
        'Mark' => 400,
        'lastUpdated' => '2010-03-17 15:44:12'
    ),
    '00357' => Array(
        'id' => 1,
        'Mark' => 500,
        'lastUpdated' => '2010-03-17 15:44:12'
    )
);

Output:

Array
(
    [00277] => Array
        (
            [id] => 3
            [Mark] => 400
            [lastUpdated] => 2010-03-17 15:44:12
        )

    [01081] => Array
        (
            [id] => 2
            [Mark] => 420
            [lastUpdated] => 2010-03-17 15:44:12
        )

    [00357] => Array
        (
            [id] => 1
            [Mark] => 500
            [lastUpdated] => 2010-03-17 15:44:12
        )

    [00358] => Array
        (
            [id] => 6
            [Mark] => 500
            [lastUpdated] => 2010-03-17 15:44:12
        )
