There's a variable $default_sort_order = '[ "position", "top", "right", "bottom", "left", "z-index", "display", "visibility", "-webkit-flex-direction", "-moz-flex-direction", "-ms-flex-direction", "-o-flex-direction" [...] defined in https://github.com/csscomb/csscomb-for-vim/blob/master/plugin/lib/csscomb.php https://github.com/csscomb/csscomb-for-vim/blob/master/plugi..., so I guess that's what CSSComb uses, although it says one can define custom orderings. I guess it's useful if you write lots of CSS and don't want to bother with thinking about the ordering at code-time?
