Requesting list=categorymembers with cmdir=descending for a category with page and subcats will give you page first, but cmdir=ascending also gives page as type first. The types should also be reversed, when requesting descending order.
Actually, no matter what the sort direction it gives back the types in the order in which they are specified in the cmtype parameter. So if you specify cmtype=subcat|page, you'll get the subcats first. Is there any particular reason the passed list of types should be reversed when cmdir=descending is given? At any rate, this would be easy to do if there's a reason to do it. Just pass $queryTypes through array_reverse() if necessary, somewhere around line 97 in the current version of ApiQueryCategoryMembers.php.[1] [1]: https://git.wikimedia.org/blob/mediawiki%2Fcore.git/a5502893899a3a71fdfa62f4692dea752bef2eee/includes%2Fapi%2FApiQueryCategoryMembers.php#L97
The request was without cmtype, so the default array was used and not reversed. But it looks hard to determine, if the three values was set by client or is the default.
The order of the grouping isn't really relevant or related to the actual query; you can process or display them in any order you wish. I'm going to go ahead and close this out as 'invalid'; as noted above if you want the items in a particular order you may ask for them in that order.
