maybe you can use the function "usort":

class Genre {
    private $genre;
    private $count;
    ...

    public function __construct($g, $c)
    {
       $this->genre=g;
       $this->count=c;
    }


    public static function compare($a, $b)
    {
        if ($a->count < $b->count) return -1;
        else if($a->count == $b->count) return 0;
        else return 1;
    }

    ...
}



$genres= array(
  new Genre (1, 5),
  new Genre (2, 2),
  new Genre (3, 7)
);

usort($genres, array("Genre", "compare"));
