Hi,
I have such plugin, although it doesn't calculate average score but this requirement you can easily fulfil on your own by simply make the calculations in the templates. GT template syntax is powerful enough for such type of calculations depending on your criteria of averageness.
PM me if you are interested and want to discuss it further.
Cheers,
Boris
