It won't let me attach more than one file so I uploaded them all to my domain.
This is the .mesh and .phys in the mesh editor:

This is in the edit mode of the world editor. I inserted the .mesh and .phys at original 1.0 scale just for comparison's sake. Clearly the phys is correct here:

This is in the world editor, edit mode. This is the interior of the .mesh. It is a hallway:

This is in the world editor, edit mode. This is the exterior of the .mesh:

This is in the world editor, edit mode. This is the exterior of the .mesh in object mode. You can see the scale change to 2.192 and the .mesh and .phys preview:

This is in the world editor, game mode. I am showing this just as an example. I scaled this castle to be 5 times larger than the original inside the world editor and you can see that the .phys scaled with the castle, so I'm not understanding why it won't with the hallway (I've also placed several objects and scaled them in the editor and the .phys has scaled with them as well):

These are both in the world editor, game mode. Here you can clearly see the .phys is in empty space, extended far beyond the .mesh itself:

This is in the world editor, game mode. Here you can see the .phys is correctly fitting the .mesh. This is at the farthest end of the hallway. The .phys seems to have scaled to be much larger than the hallway when I scaled the .mesh:

This is in the world editor, game mode. Here you can see how the .phys has extended beyond the .mesh:

I'm baffled because I've never had this happen before. I've scaled several things and this is the first time the .phys went screwy and didn't scale correctly. I even tried to scale the .mesh in the mesh editor instead of in the world editor, saved both the .mesh and .phys, and they didn't show up as scaled in the world editor.
