I see two possible problems with your code:
the MIPSolverException is not imported by Sage by default, so you have to import it first:
sage: from sage.numerical.mip import MIPSolverException
when you write
....: except MIPSolverException:
you have to do something with it, like:
....:         except MIPSolverException:
....:             print 'n is not large enough
or, more simply
....:         except MIPSolverException:
....:             pass
