In the past I've used CCTV cable for this sort of thing. Have a look at this for an example:

The challenge will be finding somewhere that will sell you a small quantity. I don't have any here, unfortunately.
Alternatively, you can make your own cables to any specification using braided sleeving. For example:

Of course, a bit of heat-shrink is needed at both ends to stop it fraying. Or you can fold it in on itself and tie-wrap it, or you can heat the ends to melt them together. I use this stuff a lot, and like it.
I don't expect that an overall screen is necessary, but the audio line obviously should be screened from the adjacent conductors. The braided screening on the video cable linked above does look a bit frail, but you'd have to test it - obviously the circuit impedances will dictate the amount of pick-up that you'll get.
