For example, let's say my browser is set to open two tabs to webpage1 and webpage2 when I first launch it. Let's say that webpage1 is the foreground tab initially but I immediately decide to click on webpage2 while both pages are loading. Changing the priority of the objects to reflect this was an easy thing to do with priority groups but I'm fuzzy on how this would work using Jeff's priorities proposal.  Can someone clarify?
