I think the test result here is correct. In the ECMA spec, subtraction uses
ToNumber, not ToPrimitive, but the test file says this, where the second test
is the failing test:

shouldBe("+MyObject", 1); // toNumber
...
shouldBe("MyObject - 0", NaN); // toPrimitive

Addition uses ToPrimitive, and the result of the equivalent addition test may
be wrong, but that's a different question.
