this just won't work in the way you want.
when you specify pattern [0-9]{2}, match() looks up first occurrence of two digit number, then continues search from that place on. as string length is 3, obviously it won't find another match.
you should use different algorithm for finding all two digit numbers. I would suggest using combination of your first match and do one more with following regex
/[0-9]([0-9]{2})/ and combine sets of both first and second run.
