Losing on Purpose to Gain Advantage

[TheFish]

Scenario:

Current Rankings:

1. Team A
2. Team C
...
30. Team B

Team A is the "best" robot in the division.
Team B is the 2nd best robot in the division.
Team C is the 3rd best robot in the division.

Match:
Team C and B vs. Team A in the last match of the day. Between A and C, whoever wins the match gets the Top-Seed.

If Team C and B win that last match, then Team C gets the Top-Seed, will then pick team A and lead to a division victory for them.

If Team A wins the last match, they get Top-Seed, will then pick Team B, leading to a division victory for both of them.



The question:
Is it appropriate for Team B to lose the match on purpose, knowing that it will greatly improve their chances of winning in the end?
