Unfortunately this doesn't seem to me to work:

358: B>C | A
305: C | A>B
187: A | B>C
148: A>C | B

A is the IRV winner, C is the approval winner, and C beats A, so C wins.

Add 35 more of the C-top ballots:

358: B>C | A
340: C | A>B
187: A | B>C
148: A>C | B

Now B is the IRV winner, C is still approval winner, but B beats C, so B wins.
