yeah the curving scratches are very odd. it might be that they are originating from something else than the camera gate area unless the pressure plate is wobbling around a lot.
if you have access to the original negative you can check which side the scratches are on and which kind of pattern/interval the wobbling scratches have, that may add some light to the origin of them.
the curving scratches seem to have a repeating pattern which might be caused by a roller for example (a lab issue??) or the film moving around side to side in the film channel either feed or takeup side when something is scratching it (a mag issue) .
gate scratches are normally happening only if you have a bad DIY super16 modification which has left sharp edges to the gate. and with this type of cameras (SR series) the gate scratches should not curve/move around at all, they should be straight lines...
as Tyler said it would be easiest to first scratch test the magazine and if that has not issues, then look for a lab issue
