It's the case that MS Windows does it the other way around:
^ means values are currently sorted from low to high (going
down the column). IOW, the triangle _reflects_ the current
sort order - it is a depiction, in a way, of the sorted values.

To me, that makes more sense. But I agree with this statement:

Still, for some kinds of data looking quickly at the topmost few
values might not be as quick as looking at the column symbol,
once you are used to its meaning.

If this is mainly (only?) a platform thing then maybe Emacs
should do something different for different platforms - dunno.
