Can Morality be Numerically Quantified?

So, there's a new book out - "The Moral Landscape" by Sam Harris.  Let me say first that I have not read it, but it was featured on The Daily Show during an interview with the author:

So, I guess the question is, is it possible to quantify moral acts?  I guess in some ways we already do this with the penal and civil courts - awarding money to victims or sentencing time for criminal behaviors.  Could a working scale be developed as a means of establishing a secular moral code?  It's an interesting question - one that had never occurred to me before.  Thoughts?
