Order wp_list_comments by popularity

I have a plugin to add a 'like' to a comment, each 'like' is stored in a table called likes_comments, I'm trying to sort the output of wp_list_comments according to how many likes each comment has, I'd like the comment with the most likes to appear at the top.

Here's what I'm using to call wp_list_comments:

<?php global $wp_query;
    $comment_arr = $wp_query->comments; usort($comment_arr, 'comment_comparator');
    wp_list_comments('callback=my_callback', $comment_arr);
?>

And here's my function:

function comment_comparator($a, $b)
{
$compared = 0;
if($a->likes_comments != $b->likes_comments)
{
    $compared = $a->likes_comments < $b->likes_comments ? 1:-1;
}
return $compared;
}
if($a->likes_comments == 0)
{
$compared = $compared2;
}

I'm completely stuck with this, any help at all would be greatly appreciated.

In order this to work, place the code in functions.php AND in and in comments.php (you need to find the exact placement location, before calling wp_list_comments() in comments.php):

functions.php: 

function comment_comparator($a, $b)
    {
        $compared = 0;
        if($a->comment_karma != $b->comment_karma)
        {
            $compared = $a->comment_karma < $b->comment_karma ? 1:-1;
        }
        return $compared;
        }

comments.php:

global $wp_query;
    $comment_arr = $wp_query->comments;
    usort($comment_arr, 'comment_comparator');
    wp_list_comments('callback=gtcn_basic_callback', $comment_arr);

Important note: This procedure is valid when using the plug-in comments rating (thumbs up - thumbs down). Read additional info here.
