I'd say that this problem seems really "potential" and I don't expect this to happen at all, but who knows. You could check this by looking if there is another town/city with is tagged capital=6 within the same admin boundary. If there is not, you would assume that A is also the capital for the level 6. The same logics could be applied for other levels. I agree that this is not completely fail safe, as our data in the area might not be complete hence leading to wrong assumptions (not to wrong data!), but I would prefer to take this risk in exchange for easier data evaluation with single values in "capital".
