Comment:

 [attachment:37128.diff] adds a function `wp_list_sort()`.

 The patch also adds another private function `_wp_list_sort_callback()`
 which is used by `usort()` in the main function. The fields to order by
 are temporarily stored in a private global `$_wp_list_sort` which is only
 available while `wp_list_sort()` is doing its work.

 As far as the parameters work, they are similar like the `$orderby` and
 `$order` arguments of `WP_Query` for example. One can either pass
 `$orderby` as a string (field name) and `$order` (`ASC` or `DESC`) or
 alternatively only specify `$orderby` as an array of `orderby => order` to
 support sorting by multiple fields.
