Comment:

 The codex does indicate that it is possible to pass an array to 'orderby',
 though:

   '''Mulitiple orderby/order pairs'''
   'orderby' => array( 'meta_value_num' => 'DESC', 'title' => 'ASC' ),
 'meta_key' => 'age'

 In the description of "Order & Orderby Parameters" the codex also states
 the following:

   '''order''' (string | array) - Designates the ascending or descending
 order of the 'orderby' parameter. Defaults to 'DESC'. An array can be used
 for multiple order/orderby sets.

 But when passing an array to 'order' I receive the following warning:
   Warning: strtoupper() expects parameter 1 to be string, array given in
