I think, there is no way to do this with native WP_Query [[LINK href="http://codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters"]]http://codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters[[/LINK]] You should change priority as meta filed instead of taxonomy: [[LINK href="http://www.wpquestions.com/question/showChronoLoggedIn/id/9599"]]http://www.wpquestions.com/question/showChronoLoggedIn/id/9599[[/LINK]]
