Matt Cutts Interviewed by Eric Enge
Here's the section with Matt's comments about 302s...
Matt Cutts: 302s are intended to be temporary. If you are only going to put something in place for a little amount of time, then 302s are perfectly appropriate to use. Typically, they wouldn't flow PageRank, but they can also be very useful. If a site is doing something for just a small amount of time, 302s can be a perfect case for that sort of situation.
