How to make value in ascending order in the mysql?

I want this type of output to fetch task_name from database like in this format

Task 10 Task 2 Task 3 Task 5........

My Query is

 SELECT task_name, section_name, ref_student_id
 FROM scores
 WHERE ref_student_id = '".$studentid."'
    AND section_name = 'sm1'
 GROUP BY task_name

So I want to output like this..

Answer 1

use this

"SELECT task_name, section_name, ref_student_id
 FROM scores
WHERE ref_student_id = '1'
AND section_name = 'sm1'
GROUP BY task_name
ORDER BY cast( SUBSTRING( task_name, 5 ) AS unsigned ) ASC"
