I start with a question, but not an how-to question, because I am puzzled by why such a routine is missing.

Why does Maple not have  generalized Schur (real and complex) factorizations with reordering?  The nice solution of many dynamic equations requires this factorization because the lhs is singular. MatLab does have such a routine. At the moment, it seems, one has to have accessible and connect to MatLab or NAG or LAPACK for such routines.

Is this in the works? If not, is there a reason why not?
