Yes, you can do this by repurposing the Duration/Estimate field. If you use that field as your priority value (with 1 being the highest priority), a context mode view sorted by duration will give you your tasks individually sorted by priority, across all the projects in the view.

Personally, I prefer to flag the most important handful of tasks, do them first, then grab the next batch. I do the flagging as I review, and as I look at the forecast view (iOS only, but you can make perspectives on the Mac that do much the same thing).
