Marauder's Map, A History; Wasn't Wormtail Worried?

Would anyone else like to know how the Marauder's Map came to be in 
Filch's possession?  Filch apparently confiscated it from MWPP or 
from whomever they left it to.

I'm wondering why Wormtail wasn't worried that he'd be spotted on the 
MM when he entered Hogwarts as Ron's pet.  If the map was confiscated 
before Wormtail left school, I guess he felt safe.  Filch obviously 
didn't know that the map could do, or he would have been using it to 
catch students.  

But if MWPP left the map to other students, it looks like Wormtail 
would have worried about being caught because he wouldn't know the 
map was in Filch's office.  Maybe he felt that he had no choice but 
to risk it?
