 * Hello,
 * I would like to sort the posts by a custom function.
    How could I do that?

 * Assuming a post’s average rating is saved in the postmeta table somewhere, include
   the associated keyname as a “meta_key” argument, but do not supply a “meta_value”
   arg (unless you want to limit posts to those with that one value). Then for the“
   orderby” arg, specify “meta_value_num”, assuming the saved ratings are numeric.
 * If the ordering criteria does not exist in the DB and must be calculated on the
   fly, you could apply a custom sorting algorithm to the query’s `posts` property
   by using PHP’s `usort()` function.

 * Thank you very much! You helped a lot! 🙂
    I used to use the usort() function,
   but for some reason I didn’t think of it now.
 * Thanks again! 😉
