I'd probably do the same as Dill (but I have yet to actually use the spec to tank), with the exception that I'd put the point from Rune Tap into Hysteria. Of course, I'm only thinking in a Heroic context. Raid and Heroic specs, realistically, have a few differences (and if we look at specific raid encounters, they change even more). It's just so fun to see what happens when you put Hysteria on a DpS. :P And it can be VERY helpful on some bosses in Frozen Halls, since you probably will only get off 1 (at max 2) Rune Taps in that time, but bumping 4K DpS to 4.8K DpS does mean 30K more damage in 30 seconds, which can mean a noticeably faster fight (especially if you end up groups like I do, where you have one 4K DpS, then you are the second as the tank). If the other three manage 6K DpS, that's still 5 seconds faster. Lately, it is rare they do for me (usually about 5 or so, including my DpS).
Also one note, Spell Deflection is unusually helpful in Frozen Halls, where MANY trash packs and some of the bosses have hard-hitting spells. But a skilled group (and tank) can interrupt many of these, and there is still only a 20% chance or so to mitigate the damage. It can be considered, though. Especially if you don't have hate problems, but you have some severely stressed healers in those instances. If you don't use your second spec (and already have DS) you may want to consider making a second tank spec that specifically takes it over SD just for those. Most notably, the trash packs after Ick in PoS.
[EDIT]
I as stupid and fixed something.
