I'm not convinced that playing red is worth the problems that you're getting with your mana base. There are so many tapped lands that you're really vulnerable to aggro decks. Paying two life to play an untapped land against aggro is maybe even worse. I see that you have Anger of the Gods in the sideboard, but I wonder if you'd be better off as straight Golgari.
It's very complicated trying to get this to work as a three color deck. Unless the mana can be reworked to get more basics in the mix, I would abandon this as a three-color deck unless you're just splashing a few late game cards off of your Sylvan Caryatids and at most 4 CIPT lands -- for example turn the Blood Crypts into Swamps, the Stomping Grounds into Forests, and leave the Temple of Abandons. That means that you couldn't really play Anger of the Gods, however, and then you'd be better off turning Dreadbore into Hero's Downfall, dropping your large Rakdos creatures for other options, increasing Pulokranos and Reaper of the Wilds and turn Xenagos into Whip of Erebos.
If you want to stay Jund, then I think that you have a few too many high cost creatures and that your potential card draw in Blood Scrivener is not going to be as effective as Read the Bones. With so many expensive creatures, it seems like you'll be stuck with some creatures in your hand that either you can't cast because you don't yet have the mana, or because you don't want to overcommit to the board. If you don't end up with an empty hand then Blood Scrivener could be something much better for two mana.
For minor changes, I would go to four Sylvan Caryatid and cut a Voyaging Satyr. The Caryatid is better at blocking small aggro creatures and the hexproof is great against a small red deck that would like to remove blockers or make specific creatures not able to block. If you were playing Nykthos then Voyaging Satyr certainly has a better role.
I need to stop thinking about this and get back to work, but I'll post more over the weekend.
