If you build CVXOPT from source and include the glpk module, then
cvxopt.glpk.ilp solves integer linear programs,
From a terminal type
$ pydoc cvxopt.glpk.ilp
which will give you a self-explanatory description of the interface.
If you have mosek installed, you can also use the cvxopt.mosek.ilp
routine.
