In practise I find I clearly prefer mouse up = clockwise, which is the
relation that you just called unintuitive (and I think I would agree
with you -- there's no very good reason to suppose that preference in
mouse movement would be the same as preference in how a vertical
selection responds to rotary control, but it's interesting to find
they actually do differ). My preference might be just familiarity, or
it might be my vision in the absence of any other cue aligning the
movement of the mouse with that of the left edge of the knob.

test some rotary controllers to remind myself
which behaviour my hand
expects, and it turns out it's up = clockwise.
That's a funny thing, because I've been looking at some radio equipment
with a big rotary knob to scroll through menu options. Turning the knob
clockwise moves the pointer up, and turning it anti-clockwise moves it
down - utterly unintuitive! Perhaps it's because the scrolly knob is to
the right of the display, so the edge of the knob that moves up should
"follow" the cursor?
