Newer versions of Carcassonne (or perhaps it's one of the expansions) contain scoring tiles, to track how many times a player's score-keeping meeple has gone round the scoring track, so that 50 or 100 points need to be added to the score the meeple indicates.
Before that, I've seen (and used myself) an alternative way of tracking that: placing the meeple in another position than both feet down. Either balancing on one foot and one hand, balancing on one hand and its head, or lying flat.
Is there an established rule of which position indicates what?
I've always used hand+foot: +50, hand+head: +100, lying flat: +150.
