Actually yes I have used a build similar to that. Here are a couple of the things I personally pull from that experience.
You can toss an extra DC out when you get your RP full charged.
Rune Tap is ok for doing some solo stuff and pvp however it really isn't worth it w/o IRT imo.
Most of your damage from blood will be with white strikes (normal swings) therefore you are gimping yourself by picking up Black Ice. You dont do as much shadow damage to make it a worthwhile talent say over BCB and you do even less damge with your ice attacks.
I know you are enhancing your IT with IIT and Black Ice however I found that a more common build like http://www.wowhead.com/?talent#jfVMVh0IsbRfostZfMhhxM
will create more damage.
You get plenty of extra damage added to what gives you the biggest chunk of your dps and lots of crit (you should crit anywhere from 1/3 to 1/2 of all your strikes self buffed).
You also get a nice addition in MoB although some people debate taking that skill so w/e you feel benfits your playstyle.
Also DRW can be exchanged for UB as well however since UB is kinda situational and relies on you staying in range of your target the whole time for maximum dps once again this is up to your playstyle.
Now having said that I used a build exactly like yours and found it to be competitive but not as much as the one I linked that I currently use.
This build also is not really pvp friendly as you lack some elements that are needed for pvp. Namely IRT. If you are going to spec into blood for pvp there is no reason not to take 3/3 in that skill imo.
You also neeed some dmg reduction i.e. Toughness or Anticipation however neither will make or break your build. I have to say though I don't pvp much with my DK so that isn't my specialty and as such I will leave that discussion for someone else.

In short, it's not the most optimal blood pvp spec.
You're missing out on some key self healing moves in blood (3/3 imp rune tap, Mark of blood).
Digging that deep into frost is only beneficial if you're after Lichborne and Endless winter (something like this for blood: Clickie
Due to Blood only using Death coil and Icy Touch that deal frost/shadow damage, Black Ice is not reccomended.
Necrosis is very weak in pvp due to low time on your target, unholy command is much better. (17 points in unholy should look more like this
I'd reccomend either a blood/frost/virulence build
, or a Blood/Unholy(17 for pale horse)/toughness build
it's possible to ignore toughness and choose DRM or SD.
Edit: Think he's talking about PvE? I got the impression he wanted a pvp build >_>
