R (which began life at Auckland uni) can do oodles of stuff and could
handle that with ease, and, of course, it can do pretty-well any stats
calculation -- and is the best graphing software I've seen.  There is
a fair bit to know about using it, so it's probably not worth learning
its idiosyncrasies for such a small task if you have awk type skills
already.  

But if you're interested, I've had quite a lot of experience with R
and would be happy to help make a little script -- particularly if you
want to make graphs as your output.
