What the author brands "consequentialism" sounds like a more narrow brand of utilitarianism. Consequentialism is about more than minimising suffering or maximising happinesses. First we need to find our actual utility function, then maximise that. Of course, it doesn’t help that we humans don’t quite have a utility function, let alone know what it is. My point being, I don’t think retributivism and consequentialism are incompatible, to the extent "balancing the scales of justice" is a significant part of our utility function. Retributivism and (old fashion) utilitarianism are.
