You will probably need a HABTM setup like this:

Class Tag extends AppModel {

    public $name = 'Tag';

    public $hasAndBelongsToMany = array(
        'Article' => array(
            'className' => 'Article',
            'joinTable' => 'articles_tags',
            'foreignKey' => 'tag_id',
            'associationForeignKey' => 'article_id',
            )
        );
}

Class ArticlesTag extends AppModel {

    public $name = 'ArticlesTag';
}

Class Article extends AppModel {

    public $name = 'Article';

    public $hasAndBelongsToMany = array(
        'Tag' => array(
            'className' => 'Tag',
            'joinTable' => 'articles_tags',
            'foreignKey' => 'article_id',
            'associationForeignKey' => 'tag_id',
            )
        );
}

Add following to your AppModel, you will never look back:

class AppModel extends Model {

    public $actsAs = array('Containable');
}

In controller:

$results = $this->Tag->find('all, array(
    'contain' => array('Article)
    ));

$this->set('results', $results);

In view:

<ul class="tags">

<?php foreach ($results as $data) : ?>
<li class="tag"><?php 

echo $this->Html->link($data['Tag']['name'] . ' (' . count($data['Article']) . ')', 
    '/tag/' . $data['Tag']['slug'],
    array('title' => 'View articles for ' . $data['Tag']['name'], 'escape' => false));

?></li>
<?php endforeach; ?>

</ul>

Hope this helps.
