Looks interesting.
Maybe you should fork my gist so we can golf on two courses, because both approaches seem fundamentally different. And don't forget the "annotated.js" file :-D
Edit: One more thing. The algorithm says "Two adjacent letters with the same number are coded as a single number.". I thought "555" should get "5" but obviously "55" is correct. So we both can strip the plus sign in our regex.
Edit2: LUS ftw!

What was the idea behind "toUpperCase"? Remove it and subtract 98 instead and BAM 146 bytes.
I wanted to make my function case insensitive but, yes this is Spa^W140bytes and surely I can get away with that. Thanks

:) That was fast! Nice move getting rid of the replace(...)
A little too late (things have moved on, I see), but for the record: I did not intend to remove the backslashes. It was probably a copy-and-paste error. Sorry about that!
I got it down to 133 : https://gist.github.com/1263293

Good idea. Will commit.
But you removed one of the two backslashes in the regex ("\d" and "\1"). They are needed. I will add a test case for that.
Edit: I guess GitHub removed them, just as in my comment. Maybe we should use the appropriate Markdown for code in future.
