this isn't the surgery board. maybe you should go ask over there if you are trying to get Surgery.
as for USMLE scores, i dunno if you can just generalise, because like others have said, there are many factors used as valid criteria for recruitment.
someone with a 230 and now particular interest in Path may not be selected over someone with a 195 and a genuine interest in Pathology.
things aren't so cut and dry. If it were something like Radiology, then you can safely say that an IMG would have to have a 240+ to be considered due to the competitiveness, but Path is not an uber-competitive field.
so the miscellaneous factors play a bigger part.
