The map can't be selective against Marauders because Lupin saw Pettigrew on
it, it's the reason he realized Sirius wasn't the killer. The reason Harry
never saw Sirius on it was that he never looked at the map while Sirius was
inside Hogwarts grounds. Sirius only snuck in once, the night he tried to
attack Pettigrew the rat and Ron woke up screaming, right? Harry wasn't
looking at the map, he was asleep. As for Pettigrew, well, Harry didn't use
the map all that often and when he did, he wasn't looking at the areas where
Ron happened to be nor the Gryffindor tower where Pettigrew probably stayed
most of the time. I think we can probably count on one hand the amount of
times Harry used the map, it's not that improbable that he didn't see
Pettigrew on it.
