When you say base score, do you mean the score seen in the diplomacy window? And by final score, do you mean the one the game shows you when it ranks your performance from Quayle to Augustus, or the one in the HOF (which differ by a couple percent). Just trying to get this terminology locked down.

As far as I can tell:
- The diplo window shows you a Base Score. If you hover over it you can see that it is built up from your cities, pop, land, wonders, tech and future tech components. I don't know how the numbers are derived from your raw demographics. I can recover that Base Score from a Civ5Save or from a Civ5Replay file.
- In your Hall of Fame window you will see your Final Score for the game. This is recorded in the Civ5Replay file, but not in the Civ5Save file. I expect it is calculated from the Base Score components, plus a bonus factor relating to your finish date and perhaps game parameters such as map size, difficulty, speed ....
- When you see the Dan Quayle window, you and your opponents get a "Ranking" number. It isn't called a 'score' as far as I recall. In my game it was about 3% higher than the HoF score. There are some entries in one of the XML files that may be used to calculate it, but I don't think it is used for anything other than this window. I have not been able to find it stored in the save or replay files. Unless someone tells me I'm wrong, I am going to ignore it for competition purposes.
Apart from the arrival of the Dan Quayle "Ranking" number, this all looks very similar to the Civ4 scoring system, except that the Final Score formula was visible in the Python/XML in Civ4, but it seems to be hidden away in the DLL in Civ5. And we don't have the DLL code yet, of course.
If we define a score-related awards and ranking system, then it will probably be based on the HoF Final Score, but I will need to discover how to calculate it from data in the Save file. I want to avoid asking for replay files to be submitted along with final saves if and when we hit full competition mode.
