OK. For the --avoid options, things are clear now.

Regarding the modules to include:

So, it looks like the original gnulib-tool does some sorting of the
module names that gnulib-tool.py does not do yet, in some earlier
processing steps. Since this can affect other parts of the output,
it would be good to have the sorting at the same processing stage.

None of the 'sort' invocations in gnulib-tool are covered by an
entry in the gnulib-tool.py.TODO file. Therefore the most promising
approach to finding the cause of the difference is to
  - go through all 'sort' invocations in gnulib-tool,
  - find the corresponding place in pygnulib/ and see whether
    sorting happens there as well or has been forgotten.
