Sorry for the late reply, just saw this...

BitLox works in Tails by running a script that downloads and installs iceweasel from the debian sources.
Once it's downloaded, you install the plugin and access your wallet via the web app.

I just tested it out again this week, it's good to go on the current Tails (2.7).
Oh, and it works with any generic Tails copy, no specific to our set which uses an encrypted USB stick.
