I just checked the alliance score chart using the alliance statistics button. By score, Murder Inc. should be fourth after TPF with a current score of 13.76, yet at the moment it is behind Roman Empire at 13.68 and United Nations at 13.6. These are the scores popping up when I mouse over the bar chart. Either the chart is ordering wrong, or it's grabbing different scores from what it's displaying.
I printed the chart as a PDF, but there's no more mouse over so it's probably useless... heh.
