cupsGetNamedDest was created specifically to avoid getting the whole printer list because that can take a long time (comparatively). I will investigate a separate fix for cupsGetNamedDest that uses the lpoptions default over the system default.
That said, The inconsistencies reflect the desires of Linux distributors, users, and Apple - originally there was One True Default printer, maintained by the administrator for the system. Then one could set a network default if no local default existed. Then we needed user-savable options and defaults. Then we needed to be able to set system-side defaults. Then we wanted a last-used-printer scheme if no user default was set. Aaarrrggghhh! (http://www.youtube.com/watch?v=avpFGlv7iw8)
