Had disagreement with one of the players who felt that when player B draws the tile, he uses the 10 points for exploration, and that player c was the first person to score. Thus player B would be the final player to score in the game.
The player you had the disagreement with is correct. Mind you that as there are 36 tiles in the game the last player in the initial turn order (using the basic rules) will always be the last player to draw a tile and, thus, the last player to score at the end of the game.
