I don't think the 2012+ bill has completely passed yet [Edit: almost as soon as I wrote that, there was news that the budget had been sent to the governor]. It's out of conference committee, but that doesn't necessarily mean anything considering how the governor may veto it. The bill only officially covers the years 2012 and 2013, as far as I'm aware, but there were also "base appropriations" for 2014 and 2015 listed in the most recent version of this year's bill.
[Edit: I don't know the full history of funding for metropolitan transit operations. Prior to 1996, this graph shows funding for the old Regional Transit Board rather than the Metropolitan Council. The funding structure seems to have been significantly rearranged at that point. Prior to 1996, roughly half of the allocation was specifically being directed to Metro Mobility for door-to-door paratransit operations. After that point, there would occasionally be a ceiling set for Metro Mobility funding. The appropriation in general rose by 50% from 1995 to 1996.
I'm not quite sure when the MVST started being used.]
