What locale are you using? You can print out your locale settings
with the locale command.
$ locale
Very often the locale is set to a "human" locale where case is folded
and punctuation is ignored in "dictionary" style. This ordering is a
libc system library definition.

I personally would do this with two different commands. First list
the dot files using shell file glob matching only dot files. Second
list non-dot files. I would also use the --time-style=long-iso format
so that the dates are printed consistently.
$ ls -Ald /tmp/.[!.]* ; ls -Ald /tmp/*
But I realize that sets different columns for the two different commands.

I have no idea what you are talking about. I don't recall any bug in
that area. And if it is there then bringing up a fixed bug muddies
the water.

In your example the filename is key 10 not 11.
0 -rw-------. 1 root root 0 Nov 9 15:06 yum.log
1 2 3 4 5 6 7 8 9 10
That might be the most of your problem.

Try this:
$ ls -Asl --time-style=long-iso / | env LC_ALL=C sort -k9,9 -k7,8
Then please report back in if your problem is resolved. Please keep
the bug log in the recipient list.
