For priorities, lower numbers represent higher priorities. The default priority if nothing is specified is 0.
The priority comes into play when you use the "Work Queues - Get Next Item" Action. This action will pick up the next work queue item according to Priority, and then the time when it was added to the queue. Items added earlier into a queue get chosen before items that were added later, if the priority is the same.
There are of course other methods of circumventing the default order in which queue items are retrieved, for example by using filters, so what I've mentioned above may not be correct in all situations.
