Hi Dmitri,

before I look deeper into your patch, please try the
following and tell us if this does the trick:

You can influence the sorting strategy,  The following should work:

(setq org-agenda-custom-commands
       '(("P" tags "{^score[0-9]}"
          ((org-agenda-files '("~/org/books.org"))
           (org-agenda-sorting-strategy '(tag-down))
           (org-agenda-prefix-format "  %T: ")))))

This sets up the command `C-c a P' to select books with a
score tag, and to sort the list by score.
The parameters make sure that only the file
~/org/books.org is checked, set up the sorting strategy
to only look at the tag, and change the prefix to only
show the score tag.

The one complication/limitation is that the setup above
will require that the score tag is the last tag in the
list of tags, because only that tag will be used for
sorting.  A good way to do this is to make the score
tags the last in your tags setup, for example:

#+TAGS: xxx yyy zzz
#+TAGS: { score0(0) score1(1) score2(2) score3(3) score4(4)
#+TAGS:   score5(5) score6(6) score7(7) score8(8) score9(9) }

As you see, the score tags are set up as mutually exclusive
(they are grouped in {...}), and all other tags are listed
before them.  So after changing tags with C-c C-c, tags
will always be sorted to have the score last.
