Comment (by bradyvercher):

 I just ran into a similar issue today where
 `WP_Posts_List_Table::get_orderby()` method doesn't work when doing
 `$wp_query->set( 'orderby', 'meta_value' )`. The list is sorted correctly
 when clicking a column header the first time, but reversing the direction
 doesn't work since it looks like the `orderby` query var needs to match
 the column key here: https://core.trac.wordpress.org/browser/trunk/src/wp-
