(Untested): \framed[align=normal,width=fit]{\startformula \startmathalignment ... \stopmathalignment \stopformula} math alignment is a display math environment, and must be inside a \startformula ... \stopformula. Two comments: 1. You know about \definemathalignment, right? 2. I think that this effect can be obtained more easily using \startitemize[two,columns,a] \item ... \item .. \stopitemize but you might need to insert a negative \vskip (or \blank) to get matrix to align with the item symbol.
