`10' is going to sort before `2' with that rule. Having done the whole
bitter experience thing with this, may I suggest:

        $srt =~ s/(\d+)/unpack("B32", pack("N",$1))/eg

Which will give you nice 32 bit binary representations of your
numbers, which have leading zeros and will sort properly via cmp. 

If you want a sample of the pain I had working that out, you should've
been at my 12 step perl session at YAPC::Europe.
