Incomplete answer, following up on floraline's "critical insight,"
we can rewrite the puzzle backwards as "Type of car first of thousands equal scores."
...because that's so much clearer. < /sarcasm>
But what if we treat this as a
cryptic clue where "type of car" is Model T, T is the "first of thousands.
But I still haven't figured out how to
incorporate the "equal scores" portion. Could that somehow be used as "model," as in, something serves as a model, to be tested for equality ("Model homes" would all be like the matching homes). Not sure.
But maybe this will kick someone forward. I'm bad at the sort of thing in bold in the second spoiler, so it might be simpler than I think?
What if it's a T from the car, and then the "first of thousands" is one T, which phoenetically sounds like "twenty", which is a score? I know a cryptic clue would normally indicate phonetic cues, but I'm just throwing snother idea in the pot. Also, as pointed out by celtschk, T is the 20th letter, so the relation remains...
See if that helps anyone...
