They are for me. In the Asia section, 中文 ["Chinese"] is listed first, followed by 吴语 ["Wu"] and then 粤语 ["Cantonese"]. Stroke order is first by stroke count and then by an obscure criterion that I don't know (and that, in my experience, Chinese people living in China also don't know), but stroke count is unambiguous and these are in order: 中 4, 吴 7, 粤 12.
Note that they aren't in alphabetical order: 中 Z, 吴 W, 粤 Y.
Japanese appears between Wu and Cantonese for unclear reasons.
