 Four volleyball teams are playing a single round-robin tournament, i.e., each team plays one match with every other team, and only one match. If the score of a match is 3:0 or 3:1, the winning team gets 3 points and the losing team gets 0 points; if the score is 3:2, the winning team gets 2 points and the losing team gets 1 point. The final scores of the teams are exactly four consecutive natural numbers. What is the score of the first-place team? Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
