I don’t think he’s worried by the Marauder’s Map. If he knew it could expose him he’d have already taken it from Fred and George.
Of course, there is no possible way that he does not have his exit from Hogwarts entirely planned out. But it’s still April, so I don’t think he plans on leaving quite yet.
He may not know of the Map’s existence. He may be afraid of Dumbledore having some, possibly unknown to Quirrel, spells (or Hogwarts wards) for locating people by their names.
