By the way, in the attachment you have multiple default scopes for WorkOrder. I think only one is allowed. You can order by multiple fields in one scope of course if that is what you want. Be careful with specifying the order in default scope though, it is not possible to override this (or at least it did not used to be possible) as the default scope order is applied *after* any others.
