1) More people/planets under your control that are in a good mood at the end of the game.
2) More enemy ships killed than your personal ships killed.
3) More technologies researched and stolen than other civs.
4) Better tax rate and income than other civs. (A positive cash flow each turn)
5) Time time time... the longer your civ can support the criteria above the higher the score.

Given 1 - 5, huge and gigantic with abundant planets and stars can give a veritible plethora of points and from the scores I have seen on the MV if you got the time, MV's got the beer.

A hard look is being given to the scoring system on the MV with all fixes being retroactive and applying to scores already submitted, so expect changes, especially in the area of skill level I would imagine.

Good hunting, 'till we meet that is.
