it looks like you are calling the functions correctly. i haven't seen any 
problems where this wouldn't work (although i don't think i've done any 
testing of FULLSCREEN and OPENGL actually... hmm)

you may want to check the surface flags on the screen surface after calling 
set_mode. if DOUBLEBUF didn't work, it shouldn't be in the surface flags..

screen = pygame.display.get_surface()
if screen.get_flags() & DOUBLEBUF: print "Doublebuffered"
