I wonder if it can be done on a matrix stored in extended memory? There is no direct sort function, maybe a sort using the stack?

Function MSORT in the SandMatrix does the job. You could also write a short FOCAL program that takes advantage of the SORTFL function from the OS/X module (originally also available in the CCD Module) - but that would probably mess up the header registers. The SandMatrix code is compatible with main and X-Mem locations for the matrix as well.
