10.18 (b) No run shall be earned when scored by a runner who reaches first base (3) because of any fielding error.
I think you are on the right track, but have missed the mark a bit. Jeter didnt get on first because of the error. The play was ruled a fielder's choice, but then the error allowed Jeter to reach second (without the error, Jeter would have been out). Thus Jeter wouldnt have been on base, and could not have scored. Damn. No ER for that one.
