You could use uasort() which lets you define your sorting logic and also maintains your associative indexes. Please note that it changes your original array and only returns a boolean based on success.

uasort($your_array, function($a, $b) {
    return $a['pos'] > $b['pos'];
});

My example works >= PHP 5.3 , but for older versions you can use a normal compare function as well.

See uasort() Documentation for details.
