Quick question about the scoring. is there a place on the website here that explains the Civ4 scoring? i.e. what's the difference between base score, in-game score, final score etc.?
Also, any tips on how to increase score? I certainly had tons of times to work on increasing my score!

... except I was too busy trying to figure out how to get those guys to vote for me!
There is surely a place for that, although I can't find it... The base score is split between land, population, wonders and tech. This score is then modified by the end date. Quicker victory => higher score.
The base score is the score you find when you hover the mouse above your score. There you can also see the final score if you win that turn. If you try to maximise score, then you play on until the final score indicator starts to drop.
Increasing the score is typically done by growing your cities in the end game, since pop is the easiest way to gain score. Buildings are not counted, neither are units. Try to maximise population while winning quickly.
Base score is increased with population and technology. It is not unusual for people who win the cow award to learn around 100 future techs...
Some clarifications and extensions to Erkon's answers to Arnold_T's questions (someone correct me if I am wrong):
There are only the two distinct scores, base and final. Base is not modified by time, while final score is modified by some decay function over time.
The term "Firaxis score" is used in some places, (maybe even in the game, IIRC) to refer to the time-adjusted, or final score. My guess is that when folks use the term "in-game score", they are referring to the base score, since base score is what is displayed on the list of civs in the lower right corner.
Quicker victory = higher final score,
for the same amount of land, population, wonders and tech. Since you can add land, population, wonders and tech over time, you face the tradeoff of adding scoring elements to you civ, while taking time decay penalties as you play more turns before you win. Key is to find the sweet spot, the max of the scoring function.
The time penalty per turn gets more severe the later to get into the game (or at least it always looks like that to me). In early game stages (the early BC's), I think I have seen charts of the decay function where it is actually rising and not falling, but memory is fuzzy here ... and I am so far from winning that early that it doesn't matter.
Erkon said that base score is increased by population and technology. In theory, it is also increased by land and wonders, but I assume Erkon is referring to the end of game "milking" where all wonders are gone and you can't increase land without triggering a dom victory too early. I think that pop has a greater contribution to score than the other factors (a higher weighting), so locking land below the dom limit and growing pop is the ususal milking route.
And then milking the base score, for a cow award, is different from "milking" (if that term even applies) the final score for a gold medal.
