Using the definition you provided, I don't get the same output. Are you sure you are doing what you think? The generateNumberParts=0 keeps the '12' from making it through the filter in 1.4 and 3.6 so I suspect you're not quite doing something the same way in both.
Perhaps looking at index tokenization in one and query in the other?
