So you want to do make each of the directories in your cachedir
into a python package - that means they need to have __init__.py files:

path = "pythonCache/a/b/scripts"

# ensure there are __init__.py files in each directory
# ideally, these would be in the source of the cache...
while path:
  try:
    open( os.path.join( path, "__init__.py" ), "wa" ).close()
  catch IOException, val:
    print "unable to create __init__.py in", path, val
  path, dir = os.path.split( path )

import pythonCache.a.b.scripts.plotTest
pythonCache.a.b.scripts.plotTest.printHello()
