I think this is a feature more than a bug. For the most part, sorting by priority then severity seems like the best way to approach things, unless something is extremely obviously a quick fix.
That said, the P-spectrum may have some crossover, especially at P1-P2, depending on the release cycle. For example, crashes should be focussed on a little more for always-online software, whereas for more glacial, manually-updated software, prioritising incorrect behaviour or functional issues may be more important.
