Try

  lilypond -e "(bla \"52\")" ..

it won't work for the things you're trying to do, because the -e is 
executed before the .ly is parsed.  What should happen is that default 
paper and staff size should be set with ly:get-option (see the settings 
at the top of lily.scm), so you could do

  lilypond -dstaff-size=22 -dpaper-type=\"a4\"

Any takers for a patch?  Or sponsors?
