that would be [(score * 2) - 50] * length

I don't think it is documented in the handbook, but I think there was a forum 
thread that detailed it.  It is basically as follows:

First play = (50 + percentage of length played) divided by 2

    This means a song played from beginning to end will 
    get an initial score of 75

Thereafter = (percentage played + playcount*oldscore)/playcount + 1

so a song played for the third time that had a score of 80 will score a 87

    80 * 2 = 160 + 100 =260 / 3 = 86.7

You will be able to in 1.4.1.  The new version will allow a custom scoring 
script to disable automatic scoring/
