Your MOT tester is wrong the audible warning device (horn) requires to emit a constant note regardless which way it's powered. There is no stipulation that it should run from the bikes' electrical system.

Ask around in your area for an MOT tester that knows and tests trials bikes, might be easier to get a pass.

Correct.
I took the lights off my Scorpa for it's first MOT (they don't meet the requirements anyway.) I then plugged a cheap horn into the live headlight wire and used an old kill switch to operate it on the earth side.
Here's an example fo a cheap horn. CLICKY

AS it turns out chaps the soultion is really quite simple. 
If you remove the tank and have a dig in about in the wires above the radiator you will find 2 wires about 2" long 1 blue 1 yellow which come out of the harness together with right angled spade conectors on end all you need is a 12v horn ideally from a trials lighting kit as the supply is A.C. I have used one from a montesa kit and this gives a reasonable sound.
