If it is Han characters that are being sorted, then Unicode already orders
them according to KangXi radicals (214) and (additional) stroke count.
Characters with simplified radicals immediately follow those with the
traditional radical.  Ties in these orders are broken by using the orders
of KangXi Zidian, Dai Kanwa Ziten, Hanyu Da Zidian, and Dae Jaweon in
this order.  To quote the relevant passage from the Unicode standard,
volume 2 (p. 14):

  "When a character is found in the KanXi Zidian, it follows the KangXi
  Zidian order.  When it is not found in the KangXi Zidian and is found in
  Dai Kanwa Ziten, it is given a position extrapolated from the KangXi
  position of the preceding character in Dai Kanwa Ziten.  When it is not
  found in either KangXi or Dai Kanwa, Hanyu Da Zidian and Dae Jaweon
  dictionaries are consulted in a similar manner."

Total stroke-count and four-corner (et al.) orderings are typically
used only for input mechanisms.  It is trivial to transform Unicode
Han encodings into any of various weighted indexes for sorting by using
a simple table lookup.

If anyone is interested in obtaining a Unicode Kanji Database,
I have one available for interested parties.  It contains the following
information:

  Unicode to JISX0208 Mappings
  Onyomi pronunciation(s) in katakana of each Unicode Kanji.
  Kunyomi pronunciation(s) in hiragana of each Unicode Kanji.
  Romaji for each on/kun kana reading (yomi).
  Radical, total stroke count, and added stroke count of each Unicode Kanji.
  
  *Only those Unicode Han characters which are also in JISX0208 are
   present in this database. 

Please send mail to <ucjis-request@metis.com> if you would like further
information.
