Help with Akex Star Rating 1.7 version

I am using this ajax rating system 1.7 at my site. All is working fine but I couldn't figure out how to pull TOP 10 programs that are best rated.

Here's the code:

<?
function getTopRated($limit, $table, $idfield, $namefield){

$result = '';

$sql = "SELECT COUNT(ratings.id) as rates,ratings.rating_id,".$table.".".$namefield." as thenamefield,ROUND(AVG(ratings.rating_num),2) as rating
FROM ratings,".$table." WHERE ".$table.".".$idfield." = ratings.rating_id GROUP BY rating_id
ORDER BY rates DESC,rating DESC LIMIT ".$limit."";

$sel = mysql_query($sql);
$result .= '<ul class="topRatedList">'."\n";

while($data = @mysql_fetch_assoc($sel)){
$result .= '<li>'.$data['thenamefield'].' ('.$data['rating'].')</li>'."\n";
}

$result .= '</ul>'."\n";
return $result;
}
?>

and to pullout TOP 10 or 100 (whatever limit you want) code:

<? echo getTopRated(10,'sites','sites_id','sites_title'); ?>

My table name is sites, idfield = id and namefield = title
and the ratings table is separate from sites table.
so how to I get the TOP 10 or 100 program with best ratings???

Sorry for my english
