Are you sure? That's very strange; it does get invoked on my system. This happens because turning the mouse wheel invokes mwheel-scroll, which calls the value of mwheel-scroll-up/down-function, whose default value is scroll-up/down, and those functions call scroll_command, which calls window_scroll, which on GUI frames calls window_scroll_pixel_based. Which part of this chain doesn't happen on your system?
