the very short exposure helps keep the background brightness down (more difficult with a bit of moonlight too) but after the curves adjustment it still makes the background brighter than the base image so just using lighten mode doesn't work.
i think the next step is to try video mode, as the meteors will be recorded just as bright but the background exposure will only effectively be 1/30 sec. not sure how i would process it though!

What about simply stacking all the images and then using normal masking techniques to select out the meteors and enhance them with curves etc.
Non Orionid meteors could be clone tool or healing tooled out. Would that work?
That way you are simply doing a normal callibrate, normalise, data rejection for clean up then align and median stack routine then in PS to mask the meteors to boost them then healing tool unwanted ones out.
