It's not a riddle... It's bollocks.
Glyphs don't stack and running Fire simply for Meteor Shower... /yawn
IMO... Glyph of Sacrifice is the only glyph to use with Meteor Shower. Elsewise, by the time you've actually managed to cast MS and the 1st meteor hits (~8 seconds)... the mob would be dead. It's ok if you're running Sac/Res chant as well... but a quarter of your bar to make a clunky spell somewhat effective?
