$orderby = apply_filters_ref_array( "posts_orderby", array( $orderby, &$this ) );
More Information
This filter is applied before a post-retrieving SQL statement is executed. Use it to make custom modifications to the orderby. WP_Query is versatile but there may be situations where you need to orderby a value that is in a separate database, a custom equation, etc.
