I could be making this up, but I seem to recall that command-z was chosen for its location. The z is in the bottom-left corner on a qwerty keyboard and it right next to command, making this an easy to type. Given Raskin's everything-must-be-undoable belief, this makes sense; backtracking if you do something wrong should be easy. Which, by the way, introduces another problem with localising shortcuts. Some are chosen based on their location on the keyboard, not their letter. These should (in an ideal world) be localised to the keyboard layout, rather than to the language. I'm not sure if OS X does this, but some other operating / windowing systems do.
