I was under the impression that the technology portion of the score was locked to zero until the player reaches future tech; after which points go up every time they get yet another future tech.
I've always won (or lost) all my games before reaching future tech in Civ V.
No theres a score for "technology" and one for "future technology" that is a 0 until future technology is unlocked I think Jon! I do hesitate to disagree with you given your knowledge but unless the menu is bugged that's what it says!
