I agree.  Separate the two concerns:

     import sets
     chosen = sets.Set(module.function_list)
     actuals = sets.Set([function for name, function in vars(module)
                 if name.startswith('do') and callable(function))])
     for function in actuals - chosen:
         print >>stderr, 'Warning! forgot about', function.__name__
     # now call them in the specified order.
     for function in function_list:
         function(*args)
