So that you push the dust off the edge of the disk, rather than piling it all in the center of the disk.

Because if you should mark the disc with a perpendicular line you will not impede its ability to play, whereas if you have a radial line that is not in exact orientation with the existing recorded data there is a good chance that this will interfere with the signal, thus the disc will not play.

This is because the lasers that read discs go in circles and a circular scratch from improper cleaning will cause much more damage than a straight line. Let me give you an example. I have a table that has decorative grooves that run along the edges. Sometimes a small piece of a hard substance such as plastic will get caught in the groove. If I were to try to dust in a circular motion the plastic would scratch the entire length of the groove as I dusted, doing more damage. Instead I pull the dust cloth toward the outside of the table to get the piece out of the groove. Same principle.
