There is a slight possibility that one of her scores were missed. Given when it happened we both don't think she would have scored 6 or more that round. Part of what makes this easier to not score correctly is that players could chose to not score anything in a particular round and instead trade in 1-6 of their tiles.
We record a score of 0 when someone trades in tiles on their turn. That allows us to make sure the turns are kept organized and equal.
