First, you hopefully don't access the 'TrainLevel' attribute directly?
(We have accessor methods for accessing field values - you have to use them)

Second, if you don't want values 0...N then don't use the in the vocabulary.
Using the same key and value is totally legitimate. If you need something 
else: look at the DisplayList API or write a small method returning 
whatever you need from a DisplayList either based on a key or a value. 
That's just a two-line iteration in Python (and a pretty simple Python 
exercise).
