Your description of your daughter sounds like my DD, as well as like me (even down to the IQ, lol), and neither of us have Asperger's.
If the school thinks they see something there's no harm in seeking professional advice (I agree with the others - do it privately, NOT through the school). From your description though she sounds like she just can't connect with that particular peer group, and also may be an introvert which is why she finds the environment overwhelming. Introvert does not automatically equal spectrum. I'm the same way... I hate large groups. I much prefer one on one.
Anyway, I wouldn't panic, but you could see your doctor anyway... at the very least this will make the school happy, and they'll see you as a team player (even though they're likely wrong about the Aspergers).
