But wouldn't the circular array be the one for making shells?

There's kind of another problem though too - scaling doesn't happen just to an object by itself, scaling happens around an origin point. Where would you expect the origin for the scaling to be?

I guess probably the most expected scale origin would be around some kind of pivot of the object, but as you know right now MoI does not have the concept of a separate pivot axis associated with each object.
