Sorry, I'm not following. Not sure what you mean by "the quoted text".

I was thinking that one can look in zone.tab. If the spelling is there 
it's "preferred" otherwise it's not. This heuristic won't suffice for 
arbitrary questions about "preference" (as it doesn't impose a total 
order on names) but it should be good enough for questions relating to 
backward compatibility with older guidelines.
