Hi Sanjoy,
I think it's just the 'normal' limitations you have when setting a variable/id name. Special characters, like parenthesis, are not allowed here.
Even whitespace can be problematic. Yesterday I had a problem with a reference (data driven) that has a trailing space (obviously a typo). This space was 'eaten' by TeX, resulting in a broken link. Embracing the argument helped here, but I haven't tested what happens, if you use multiple spaces in a row... indeed, references are actually a little language in their own (always have been)
