@Scott, here is the issue in a (rather large) nutshell ..
Is the scoring sequence:
1. Tile-placing player selects one of the completed features to score
2. Take turns around the table moving meeples from City of Carc to
that feature (if you wish and rules otherwise allow)
3. Determine majorities, determine fairy bonus, resolve cloister/shrine challenges, calculate scores
for that feature and move markers
4. Move any wagon(s) on
that feature - resolving multiple wagons by turns as per rules.
5. Player selects the next feature and repeat from step 2
OR is it:
First: Take turns around the table moving meeples from City of Carc to any or all scoring features resulting from the placement of the tile (if you wish and rules otherwise allow). This would occur rather like the way it is described in the rules for the end of the game.
1. Tile-placing player selects feature to score
2. Determine majorities, determine fairy bonus, resolve cloister/shrine challenges, calculate scores for that feature and move markers
3. Select next feature and repeat from step 1
Last: Move any wagon(s) on the features - resolving multiple wagons by turns as per rules.
It rarely makes sense to do the scoring in such rigid order in actual play, but when the issue arises we use the first five-step method - for the reasons given in my post.
With that approach wagon movement can be tactically manipulated by the placing player choosing one order of scoring over another - forcing another player to move or remove a wagon and leaving himself with a better wagon move in the second feature chosen.
The Count stuff hardly makes any difference except when there are a lot of meeples in Carc city and the multiple features to be scored have contests going or a big meeple subtlety placed etc. But if those conditions apply then it can make a big difference.
And it might matter even more one day in another expansion . . .
