There are many things I've never even tried on my 5D and your question 
raised my own curiosity.  I was sure that shooting raw of JPEG wouldn't 
make any difference but I didn't really know how bracketing worked.  It 
turns out that enabling bracketing sets up the *next 3* exposures to be 
normal, decreased and increased by whatever range you've set which is up 
to two stops above/below in 1/3 stop increments.  However, without 
changing the "drive mode" it's up to you to push the shutter button 3 
times.  No matter how the light changes or how long you wait between 
frames the next two exposures will have been determined by the first.

But you can also change the drive mode to continuous shooting of 3 
frames such that pressing and *holding* the shutter button will fire off 
all three in rapid succession.  And, yes, it definitely works in raw. 
And it should.  Raw images can be under and overexposed just like a 
JPEG.  It's just that raw has a bit more headroom for recovering under 
or overexposure.

If you want to break out of the sequence (as I did when I forgot to 
remove the lens cap for the first exposure) it was necessary to disable 
the bracketing.
