With a less than perfectly calibrated printer or a problem with the hot end, drawing surface hole perimeters before interiors can cause them to detach and form a string inside the hole. This problem compounds itself because on the next layer, there will be nothing for the surface perimeter to adhere to except the string, making the string into kind of a staircase inside the hole:

It would be pretty neat if it were intentional! Since it's not, Slic3r should probably draw interior hole perimeters before surface hole perimeters, which would make it match up with the ordering it uses for non-hole perimeters.
