I did some digging into the photo @Chlidonias linked and it was posted on October 17 of this year suggesting that they did indeed keep the species very recently.
Additionally, the following video posted on July 20 was linked here and gives a good look of their definite Zorilla at 10:18.
The videos shows very, very clearly that the above animal is not the same individual as their Zorilla. If I had to guess I would say that the zoo's Zorilla possibly died either at the end of October or beginning of November and they simply replaced it with a skunk. Maybe it's still bts, but either way I'm sorry to say that @drill did not see a Zorilla here.
