Retrieving the Work Item name from Work Item attribute in a script based calculated value

One answer

I'm not sure I understand your question.
Do you mean that iteration.bps is based on an Enumeration and you get the enumeration Literal back instead of the Display Name associated with that Literal? If so, then starting in 4.0, you can get getLabel() instead of getValue()

getLabel(String attributeId)
(since 4.0, to get the label of an enumeration literal)
