What for problems are you facing? Can you elaborate?

Can't confirm. I put your example in a random .tex file and hit `C-c )'
and RefTeX sees the label (which was also my expection). RefTeX looks
for a literal \label{foo} when it parses a file. In this case, it
doesn't matter that it is inside an argument.
