The only real information given about Amlaith is that he is credited as "eldest son".
You could theorize that triplets might all feel to have the same claim to the crown, and decided to split the kingdom 3-ways as an answer.

I suppose that's possible. If so, however, it must have been an unprecedented event in the history of the Dúnedain, else one would think there would have been guidelines in place to deal with it, such as the first one out of the womb being considered "eldest".

That does not appear to be the case. Appendix A to ROTK states that Narmacil I succeeded Atanatar. Being childless, Narmacil was in turn succeeded by his younger brother Calmacil.
