Seeing as he was apparently in a position of authority, I still get the impression that Quilge is stronger or more pure than some of the Sternritter we've seen, perhaps being the reason why he used the suped-up versions of the old school abilities. It is kind of hard to say given how wildly inconsistent the power levels are among the Sternritter. Well, asides from universally being able to beat the pants off a Bankai-less captain, Zaraki excluded. But heck, even his underlings used the old school bows.

On the other hand, I kind of wonder if Kubo switched things up because he felt that the Schrift wouldn't stand out enough among those powers.
