Comment (by geminorum):

 I've found no sane way to change the `WP_Terms_List_Table` default or
 custom ordering. This could be avoided if the `pre_get_terms` hook made by
 reference, much like `pre_get_posts`:

 so: `do_action( 'pre_get_terms', $this );`
 to: `do_action_ref_array( 'pre_get_terms', array( &$this ) );`

 then we can override `meta_query` with new `WP_Meta_Query` for custom
 ordering.
