Well, I've made some statistics. First of all rather simple: 89% won and 11% lost. 
Secondly, here is the division of ways of ending:
Conquest: 44%
Domination: 24%
Space Race: 8%
Cultural: 3%
Diplomatic: 4%
Histographic: 17%
And last, but not least: all the scores plotted as a function of the last turn.
