With some help from the kind folks on #zope, this has been
solved.

This was wrong in a couple of ways, here is how it needs to
be layed out:
ArchiveImages (Specialist)
traversal_method (Python Script)
defaultRack
traversal (SkinScript)
Renderings (sub-Specialist)
defaultRack
As you can see, the Python Method needed to be moved from
within the Rack up into the Specialist.

The body of the traversal_method needed to change in two
ways:
if name in ['index_html', 'editInstanceForm',
'editInstance']:
return getattr(context, name)
else:
return container.Renderings.getItem(name)
First, it needed to pass unmolested those methods of the
ArchiveImage that were needed. Second, Specialists
apparently don't support getattr(), so I needed to change
this to call getItem() instead.

The SkinScript works fine as-is.
