There's absolutely no guarantee of that, without knowing precisely what the RTOW penalty is intended to achieve for each case. If all three defects have an impact on climb capability, then they may well be additive and you'd need to combine the penalties.
But in the case of the original question, it's easy. The MEL says no multiple defects are allowed. End of.
