The old method was removed since it's wrong to force place creators to use our notifications and sounds. If you had a really spooky horror place, wouldn't the super happy victory noise ruin the mood?
The sound is still in the game files and can still be accessed by scripting. I made a example model here: http://www.roblox.com/Badge-giver-with-classic-VICTORY-sound-item?id=113412804
