As you can see on the page http://ru.wikipedia.org/wiki/Category:Математика subcategories are placed in the list in total disorder: А, М, Т, Ч, Э, again А, В, Г, К, Л, again М, Т. But the correct order is: А, В, Г, К, Л, М, Т, Ч, Э (for some letters we don't have subcategories in this category). But the list of articles sorted correct, so it looks very strange.
Fixed cl_sortkey table in the database: update categorylinks set cl_sortkey= substring(cl_sortkey,10) where cl_sortkey like 'Category:%'; Sorts fine now. Due to caching some pages are still displayed wrongly. They will be updated as soon as there is a change to the page or the list of categories.
