There's already a thread going on about CFLs and LED lights interfering with garage door remote range. Take a look at that for some general info:

I'd say to buy an LED bulb and try it. If it works fine, great. If it causes any problems, replace it with one of a different brand. You are right, CFLs are a poor choice in a cold garage. I just replaced my garage door opener light with an LED a little while back and couldn't be happier.
