Your script is something you store on the filesystem and run from a shell 
prompt. That means you have to do all the ZODB setup work and management yourself.

If you wrote a Script(Python) through the ZMI, it could do the same work but all 
the setup and ZODB management would be done for you by Zope's publisher.

Bwahahahaha ;-)

from AccessControl.Permission import Permission
from types import ListType

result = []
for pstuff in object.ac_inherited_permissions(1):
   name,value = pstuff[:2]
   p = Permission(name,value,oject)
   groles = p.getRoles(default=[])
   acquired = isinstance(groles,ListType)
   result.append({'permission':name,'roles':groles,'acquire':acquired))

Which will leave result somthing like:
 >>> print result
[{'permission':'View','roles':['MyRole'],'acquire':1}]

for the original function:
from AccessControl.Permission import Permission
import types

Bwahahahhahahahaha - no. Sorry :-(

Don't worry, your questions point out some interesting gaps in current Zope docs 
and interfaces...
