Do other New Testament books appear in different orders in ancient manuscripts even though Paul's letters don't?
Yes. Ancient manuscripts sometimes vary the order of other New Testament books, such as the four Gospels and the smaller letters at the back. However, Paul's letters consistently appear in the same exact order in every available New Testament manuscript, even though that order is not chronological.
Les explains that while other New Testament books may be in different orders—the four Gospels are not always in the same order, and the little letters at the back are not always the same—Paul's letters are never found in a different order than they appear in our New Testament today. They have always been the same. This fixed order is not chronological: Thessalonians was written first, probably then Galatians, then Romans, then the Corinthians, then Ephesians, Philippians, and Colossians, and then first and second Timothy and Titus.
