It was actually a bit more deliberate than that, especially when you look at the names for all three of them in historical terms, as all three bear a representation of religious ideologies that existed at around the 1st-2nd Century AD.
Sephirot represents the Kabbalah of Judaism just as Limecat stated, with many of the attacks named after the attributes of the Kabbalah.
Sophia represents Gnosticism, a religion based around knowledge and wisdom whose deity inspired the primal.
Zurvan represents a sect of Zoroastrianism, a religion with common themes of direct opposition (hence his fire and ice attacks and the line "good and evil, the war eternal").
