This is either a bug or incorrect documentation.
If you include pages using 'namespace' and sort by 'Page ID' the resulting pages are actually sorted by 'namespace+id'. I suppose this might be what's wanted in some cases but I want to sort solely by the page ID so from my point of view it's a bug, for others it might be a documentation error.
It's fairly obvious why the pages get sorted this way, looking at lines 742 to 749 (or thereabouts) of helper.php in the include plugin the array pages[] which gets sorted is a list of the full namespace+id of each page to be included.
