No they don't. It was a local Synod. However, the very existence of these words in the 5th century indicate that the Church was a lot more hererodox than we are willing to admit.
I don't think "original sin" as meant by Orange had the same connotations that it did after Trent. Orange specifically refutes the Pelagian notion that Adam's sin does not effect his ancestors. Pelagius said that we commit sin by example from Adam. The Church Fathers consistently refuted that, calling Adam's sin the first sin and one we inherit as being part of our human nature. St. Augustine quotes numerous Fathers when discussing how Adam's sin affects us today.
Original sin, in the West, has additional meanings that Scholasticism discovered. But this was after Orange. I don't think that the East would have refuted the canons of Orange. And if I am not mistaken, one of the later Ecumenical Councils verified what was hammered out at Orange, but I'd have to double check that (if you want).
