[antlr-interest] Distinguish between number and value

I'm using a CSS grammar and wondering how can I write a rule to distinguish between a number and a value. If I have the input "123" and "123px" I want to know that "123" is a number and "123px" is a length. 
I'm new to ANTLR and using v3. 

Thanks a lot,
A.
