 Hi, I'm trying to get results ordered by meta clauses and post date in a
 WP_Query with custom fields meta_query. It should work from 4.2 on but it
 doesn't for me. Any suggestion on the query below would be appreciated:

 Is that a bug?

 {{{
 $args = array ( [...],
   'meta_query' => array(
        'relation' => 'OR'
        'my_clause' => array(
                array( 'key' => 'any_key', 'compare' => '=', 'value' =>
 '1', 'type' => 'CHAR')
                array( 'key' => 'another_key', 'compare' => '=', 'value' =>
 '1', 'type' => 'CHAR')
            ),
         'another_clause' => array(
                array( 'key' => 'any_other_key', 'compare' => '=', 'value'
 => '1', 'type' => 'CHAR')
             )
     ),
     'orderby' => array('my_clause'=>'DESC', 'post_date'=>'DESC')
  );
 }}}
