The reason to think so is: classical physics is about movement (what is a linear relation), GR is about second rank tensor fields and QM about particles, what are in general volumetric (or three dimensional).

This all seems very arbitrary. Classical mechanics covers motion in a 3 dimensional space. It also includes second rank tensors such as the moment of inertia tensor. General relativity also contains 4 dimensional tensors of rank 1. As for quantum mechanics, it contains scalars (your traditional wave function as per Schrodinger, as well as tensors of rank 2 if you are talking about quantising the electromagnetic field.
Your ordering seems completely arbitrary. How do you justify this?
