Record objects do not implement a mapping interface.  Form elements are
turned into attributes of your 'choice' object, so your objects has
instance attributes named 1, 3, and 10.  You will need to use
_.getattr() to access these attributes since numbers are not very good
attribute names.

It might be a good idea to look into a new ZPublisher type called
:dictionary (or :mapping) that works much like :record, it would be
fairly trivial to implement, want to take a stab at it?
