To summarise, there appears to be two quite distinct questions here: a) Given there are regularities in Nature, why is our mathematics so effective. As Brent says, this is not surprising - evolution would see to it that we would choose a mathematical system out of the many possible that would be effective.
b) Why are there regularities in Nature describable by maths in the first place? This is the core of Wigner's question IMHO, and what Liz was referring to. To that end, the various proposals by Tegmark, Marchal, Solomonoff and so on are candidate answers - I won't describe my preferred solution here, as that should be well known by now.
