Can you Tween custom properties?

Question

Can you directly tween some property other than "_x",
"_y"...physical on-screen built-in properties?
Or would I pretty much have to do some trickery with event
listeners and do some calculations based on one tween to make
another tween (with easing) of some other numeric property I'm
tracking?

Using the Tween class, you mean?

Seems like it works.
import mx.transitions.Tween;
import mx.transitions.easing.*;
mc.custom = 0;
var tw:Tween = new Tween(mc, "custom", Strong.easeInOut, 0,
100, 12);
tw.onMotionChanged = function() {
trace(mc.custom);
In my Output panel, that custom property, MovieClip.custom,
updates as
expected.
