for the record, beside the python-pythonpath-pythonhome issue, by testing
the scripts r.ipso and r.wf it has been observed that there is the
python-lib-tk missing in the osgeo4w-based wingrass-installers and therefore
matplotlib isn't correctly working.

a workaround is changing the matplotlib-backend in the scripts by i.e.

 import sys
 import os
 import matplotlib <= !!!
 matplotlib.use('wx') <= !!!
 import matplotlib.pyplot as plt
 import grass.script as grass
 import numpy as np
