No, Alex, simulator time is not allowable. The LASORS references state quite clearly that the time must be on 'aeroplanes' or 'helicopters' and no reference is made to synthetic devices.
I'm not sure where the 2000TT came from; my advice to the people setting up the scheme was to use 1500hrs PIC for the ATPL(A) because that is the figure required for anyone to convert a 'national' licence to a JAR-FCL licence - and I considered anyone who had 1500 hrs PIC on ME aeroplanes should be treated the same whether military or civilian.
I would strongly recommend that the rather unreasonable 2000TT is binned but that all other LASORS D3.3 'Experienced QSP' qualifying criteria should remain.
