I don't know why <shift><pg up> and <pg down> doesn't work, but you can assign any key combination you want to this actions. In "extensions/xterm/layouts/Xresources" file there is line:
XTerm*VT100.Translations: #override \
It defines overrides for key actions. For scrollback add for example:
<Key>F1: scroll-back(1,page) \n\
<Key>F2: scroll-forw(1,page) \n\
It will assign <F1> and <F2> keys to scroll one page up and down respectively.
