Other object detection models are able to pass the test with box_tol=0.01, but here we loose it to box_tol=30 for faster_rcnn models. Do we know what causes the accuracy regression here?

I think the onnx model can predict the same objects with very similar scores. It's just with a few boxes one of the four values (xstart, xend, ystart, yend) can differ by quit a bit (refer to the bbox of the boy in red). I am not sure about the cause, but it must be related to the fpn structure.
