What makes you think Pygments can’t do this? You can do

(?<=\w+)\d+

and things like that. You could also arrange so that the regex parsing a pitch 
leaves you in a state of the lexer where something special will happen for \d+. 
However, durations don’t always follow a pitch, as in

\tuplet 3/2 8. { … }

which is the reason why we don’t want to do that.
