$data = $this->User->find(\'all\', array(
    \

I think you are getting numeric indexes on your results array because the fields you are adding haven't been generated by CakePHP. CakePHP usually generates queries (and field names) more like this in SQL:

SELECT `Item`.`id`, `Item`.`name` FROM `items` AS `Item` WHERE 1 = 1 ORDER BY `Item`.`name` ASC

You should try and mimic CakePHP's field naming conventions when adding custom elements to your queries, if you want CakePHP to better understand and format the results coming back from MySQL:

$age = "DATE_FORMAT(NOW(), '%Y') - DATE_FORMAT(User.dob, '%Y') - (DATE_FORMAT(NOW(), '00-%m-%d') < DATE_FORMAT(User.dob, '00-%m-%d'))";
$data = $this->User->find('all', array(
    'conditions' => array('User.age >' => 20),
    'fields' => array(
        $age . ' AS `User`.`age`',
        'COUNT(id) AS `User`.`count`'
    ),
    'group' => 'User.age'
));

Maybe this will give you more luck getting the conditions to work. :)
