I always two finger brake. Whenever I use four digits, I find that I use more braking that I really need, plus there's the split second that you lose repositioning your hands. I too got penalized for using this technique at MSF, but it's really something that should be encouraged as an option, rather than a no-no. To them, two-finger braking seems to carry a stigma shared by left-foot brakers: there are advantages to left-foot braking and the criticisms against its use are usually unfounded or ridiculous. Not that I discourage four-finger braking (it's a solid technique that conveys the highest potential effort); just that two-finger braking is a good alternative.
There are two varieties of two-fingering that I've seen practiced; one is common use and the other I've only seen performance riders use: index-middle and ring-pinky. I use the former 90% of the time. The latter apparently gives you better throttle control and is good for firm braking systems that require a more delicate touch.
