In that case run with it all the way to court. Sure, they'll probably get you on the mis-spacing, but then they could do that anyway and you won't be any worse off than you are now (remember, they'll have to issue a separate ticket for that offence which they can't mention in court in relation to the current 'offence'). Honestly, don't pay up and don't bother going down the station, take it all the way and wait for the look on his face when the judge/magistrate/sheriff/whatever they have in Scotland rips him a new one for being a complete idiot.
