Does the 11.5.9 workflow mailer consider the notification priority when picking up notifications for

We have several different types of notifications waiting in the wf_notifications table. We wanted to know how to make a certain notification for a particular item type be something that is always picked up first. We set the priority to High but I don't think it is making any impact. Is there a setup that we need to configure in order to make this work. We need order by priority, enq_time. We are on 11.5.9.
