The issue is that fields are held in HashMaps internally so field order is not maintained. The thinking behind this was that field order was not so important as Tuples are mainly accessed by keys. But I think it's worth looking into an approach for maintaining field order. Feel free to create jira about this issue and update this thread with the issue number.
