How to order Fixtures

They are not ordered by match date. Look http://clip2net.com/s/772XIk. I want to order by creation date, why is possible this? I think this is the code to modify, but.. how to change to order by creation date? $fixtures = new WP_Query(array( ‘post_type’ => ‘fixture’,'paged’ => $paged, ‘orderby’ => ‘meta_value’, ‘meta_key’ => ‘date’,'order’ => ‘ASC’));
