Those number for the Legions of the Romans never had any rhyme or reason that we could decipher to this day. They are based on some order that we can't figure out. They often and always seemed to change for no decernable reason.
Some believe the numbers relate to the importance of a Legion in an army, but then why did Caesar always have Legio X?

We don't know well enough how the Roman or Provincial armies worked to make assumtions on them.
