As Andrea mentioned in https://yhetil.org/emacs-devel/yp1cyssanrp.fsf@fencepost.gnu.org/, type declarations are not yet supported and it is not yet clear how long it will take to implement type declaration support. If you wish to contribute a better sorting to Emacs, another option might be contributing to Emacs C sources. Check out src/sort.c file (tim_sort) for the sort implementation that is currently in use. https://git.savannah.gnu.org/cgit/emacs.git/tree/src/sort.c#n915 -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at .
