When the computer plays a spell the
Veiled Serpent triggers like normal and becomes a creature. It still has a +1/+1 counter on it, but it is no longer a zombie.
The only thing wrong in this scenario, is the Serpent shouldn't be coming back as a Zombie at all.
205.1a Some effects set an object's card type. [...] If an object's card type is removed, the subtypes correlated with that card type will remain if they are also the subtypes of a card type the object currently has; otherwise, they are also removed for the entire time the object's card type is removed.
205.3d An object can't gain a subtype that doesn't correspond to one of that object's types.
Grave Betrayal attempts to give a subtype to the enchantment that it can't have. This may be treated as an impossible action and ignored completely by the game, rather than storing "Zombie" for later use.
