How do you orient a sphere?

I was thinking of orienting the pigment so that the brightest part of
the glow is on the line between the center of the sphere and the object
on which the radiosity "light" is meant to shine.

A glow is neither a textured sphere nor a disc and it has no orientation.

I hate to tell you this, but when I was playing with the Glows in Chris
Huff's MegaPOV+ a year or so ago (via a Moray plugin), there were a few
images posted here where glows were used as light sources for radiosity
renders.

I can never get enough of glows. But don't forget they're buggy, in their
current implementation. I assume you've had your encounter with this? I did
one test and immediately got problems. I had nothing but glows in the scene
however, but those in front introduced wrong colors of those in the
background. I suppose this is related to the problem described by
Christopher James Huff, in which he says something about they mess up the
things behind them.
At least sometimes... :o/
