I guess because it isn't magnetically shielded.

Most speakers are not magnetically shielded, so no big thing there. Most magnetically shielded speakers cost a little more because they have another magnet on the back of the driver to partially negate the field... There are a few reasonably priced ones out there, though.

For the best sound quality, do you think it's better for the tweeter to be on top (ie. with the speaker right way up) or below (ie. with the speaker upside down)?

The general rule is keep the tweeter more in line with your ear... if it's on top of the TV, you might want to put the tweeter side down. That would also have the added benefit of keeping the stronger magnet away from the TV and reducing discoloration from the magnetic interference. In reality, though, you'll probably notice very little audible difference between tweeter up or down.

I should mention that using a magnetically shielded center is probably a good idea as that interference can really screw up your picture, sometimes permanently. If the discoloration remains, however, you can always degauss the TV. There are tools to do this yourself, but most (hopefully all) TV techs will be able to do it for you with the benefit of experience.
