This patch fix the cn_sort sorting accurace described by Joy Nelson.
Testing:
I) Appy the bug 12424 patch
Before applying this patch:
0) Select 3 items.
1) Edit the items selected
2) Change "Full call number" option to 971/P23w/v.1-2/pt.8, 971.01/P23w/v.1-2/pt.6-7 and 971.01/P23w/v.1-2/pt.7
3) Save changes
4) Valide 971P23WV_12PT_8_000000000000000, 971_000000000000000_01P23WV_12PT_67 and 971_01P23WV_12PT_700000000000000 (table items - cn_sort column).
After applying this patch:
5) Edit again the item selected in 0
3) Save changes
4) Valide 971_000000000000000_P23W_V_12_PT_8, 971_010000000000000_P23W_V_12_PT_67, 971_010000000000000_P23W_V_12_PT_7 (table items - cn_sort column).

C4::ClassSortRoutine::Dewey can pad the wrong part of a call number internally.
The subroutine get_class_sort_key tokenizes a call number string (splitting on
periods and whitespace) and counts the number of tokens that solely contain
digits. If there is only one such digit group, a comment in the code states
that it will pad said digit group. However, the bug is that the code assumes
said digit group is the first token, when this may not be the case.
In practice, this can cause poor sorting when used a call number is in the form
of PREFIX _space_ 3DIGITS.
To test:
[1] Create two item records whose class scheme is set to
'ddc' (Dewey) and whose call numbers contain prefixes, e.g.,
J DVD 700.1 ABC and J DVD 850 DEF.
[2] Use the inventory tool to produce a list of item items that include
the two created in step 1. Obsere that that items are sorted
in the incorrect order, with "J DVD 850 DEF" coming before
"J DVD 700.1 ABC". Alternatively, run the following SQL
to see the incorrect sort order:
SELECT cn_sort, itemcallnumber
FROM items
WHERE itemcallnumber LIKE 'J DVD%'
ORDER BY cn_sort;
[4] Apply this patch.
[5] Run misc/maintenance/touch_all_items.pl to force cn_sort to be
recalculated.
[6] Repeat step 2 and verify that the call numbers are now sorted
corrected.

1. The current C4::ClassSortRoutine::Dewey turns "306 Les" into "306_Les" for items.cn_sort and MARC-field 952$6, which results in "306.46 Les" being sorted before "306 Les" in the OPAC. With this patch, "306 Les" is turned into "306_000000000000000_Les".
2. Currently, call_number_asc and call_number_desc are set up to sort by 1=20, but this is mapped to Local-classification in ccl.properties, which is mapped to 952$o in record.abs.
This patch changes these sorts to use 1=8007, which is mapped to cn-sort and 952$6.
