I worked on the official Racer 0.7 script and updated it so that it now uses proper stats and ranking at the stats screen:

The times are shown in milliseconds because I can only work with integers here.

I also have created some basic schemes for this script.

Here are the source codes:

Racer_v0.8.cfg: http://lpaste.net/115907
