Well, because Luna wasn't herself when she was doing what she was doing; she was possessed by an evil force (that was partially her fault, as her jealousy made her vulnerable to it) that turned her into Night Mare Moon. Whereas with Discord, it's obvious that's what he's actually like, so the Elements can't purify him; there's nothing to purify. So they turn him to stone.
