Workflow transition scripts (metatype 'Script (Python)') are 
"untrusted", and therefore have *no* access to many standard Python 
builtins / modules;  see the "Advanced Zope Scripting" chapter of the 
Zope Book:

http://zope.org/Documentation/Books/ZopeBook/2_6Edition/ScriptingZope.stx

The simplest way to achieve what you want is to make an External Method 
as a replacement for your Python Script;  External Methods are "trusted" 
code.
