But as Josh suspected, I lean more towards C++ and hence Rcpp. It also has plenty of examples.
Edit: There were two books I found helpful:
The first one is Venables and Ripley's "S Programming" even though it is getting long in the tooth (and there have been rumour...

How to sort a list of strings numerically?
... the results. What you want is:

list1 = [int(x) for x in list1]
list1.sort()
If for some reason you need to keep strings instead of ints (usually a bad idea, but maybe you need to preserve leading zeros or something), you can use a key function. sor...
