At least my P-90 vintage set it isn't RW/RP. But it is possible to make one of the pickups RW/RP once you have bought it.
1) You have to switch the ground and the hot connection
2) Slightly loose the screw of the bottom plate so you can access the magnets
3) Flip the both magnets
4) Tighten the screws again
I've done this myself and it is pretty easy, especially if you have experience soldering.
