Hmm, I think you might need a plugin for that one.
Can't you do something like this using a look ahead regexp?
(?=[A-Z0-9]{30,})(?:[A-Z]*[0-9]){10,}
The look ahead gets the 30 chars. Then the next part gets the 10 or
more numbers. You probably don't need unbounded {10,} but you do need
the {30,} part to be unbounded.
Is the 10 number part really important?
