Per Junio's email, with core.quotepath=false, there are no differences with sorting in either ls-files or the tree named in the GIT_TRACE_2 output:
$ git config --local core.quotepath false
$ git ls-tree --name-only -r 74332b7d653cde7ba3b999cc7b0adcfd9d924440 > ls-tree
$ LANG=C LC_ALL=C sort ls-tree > ls-tree-sorted-lc-all
$ diff -s ls-tree ls-tree-sorted-lc-all
Files ls-tree and ls-tree-sorted-lc-all are identical
$ git ls-files > ls-files
$ LANG=C LC_ALL=C sort ls-files > ls-files-sorted-lc-all
$ diff -s ls-files ls-files-sorted-lc-all
Files ls-files and ls-files-sorted-lc-all are identical

There is no read-tree in the output (below). The sha1 that is mentioned, 74332b7, is the one for the current trunk:
$ git svn log -1 --show-commit --oneline trunk
r231655 | 74332b7 | CLT: changed skill from not compound to compound.
So not surprisingly, I guess, I get basically the same results as with the ls-files commands earlier: files with Unicode chars are quoted and sort at the front:
$ git ls-tree --name-only -r 74332b7d653cde7ba3b999cc7b0adcfd9d924440 > ls-tree
$ LANG=C LC_ALL=C sort ls-tree > ls-tree-sorted-lc-all
$ grep -n Ninja__Beta ls-tree*
ls-tree:36974:"curriculum/Fluency/Hurix work/source from May 2014/For_Anesh/06 Deliverables/Phase 2/FT3 \342\200\223 Ninja/FT3 \342\200\223 Ninja__Beta.zip"
ls-tree-sorted-lc-all:89:"curriculum/Fluency/Hurix work/source from May 2014/For_Anesh/06 Deliverables/Phase 2/FT3 \342\200\223 Ninja/FT3 \342\200\223 Ninja__Beta.zip"
(Just sorting with LANG=C but without LC_ALL=C produced a ton of other differences, mostly around numeric vs. lexical ordering as far as I could tell.)
I tried this same thing with my test repo, and it exhibits the same quoted-filename-sorts-to-the-top behaviour, but does not exhibit the git svn fetch write-tree error.
