Use the "asof" modifier if you have specific points in the past you'd like to see. You'll have to include the scope name in the query "select" to get the historical value.
v1 = V1Meta()
past_date = '2012-11-01'
query = (v1.Story
.where(Number="S-01211")
.asof('2012-11-01')
.select('Number', 'Name', 'Owners.Name', 'Scope.Name')
)
for story in query:
print story.data['Scope.Name'] # prints current value
