I don't remeber the exact syntax and don't have time to look it up, but 
check out my MAPS article on theorems (it is also a MyWay, I think). There 
is a way to couple numbers of different theorems (so that you get Theorem 
1, Lemma 2, Theorem 3, etc), and the same syntax should work for using a 
different counter.

Another approach could be to use

\defineenumeration[Lecture][...]
\setupnumber[Lecture][numberorder=reverse]

(again untested)
