I'm not sure I understand the request.  Do you mean that the result of
this would be a list of overlays, where the first one is the overlay
of the highest priority _anywhere_ in the buffer, the next one of the
2nd highest priority, possibly in an entirely different place in the
buffer, and so on -- i.e. completely disregarding the overlay
positions?  That's a very strange order.  Which job(s) need(s) such an
order, and why?
