I'd suggest consistent naming for easier readability and sanity of the code:

"xsaver-when-paused" --> "xscreensaver-when-paused"
xsaver_when_paused   --> xscreensaver_when_paused

And I think of clarification (also in the docs) about the priority: According to 
your code, your option is effective when the screen saver is disabled and it 
overrides that setting. That's of course perfectly logical but may not be 
obvious to the user.
