Version-Release number of selected component (if applicable):
coreutils-8.4-16.el6

How reproducible:
Always.

Steps to Reproduce:
1. Issuing 'ls -Zl' and 'ls -lZ'
  
Actual results:
'ls -Zl' shows a list like followings.
# ls -Zl
total 130
dr-xr-xr-x.   2 system_u:object_r:bin_t:s0       root    root     4096 Jan  5 17:08 bin
dr-xr-xr-x.   5 system_u:object_r:boot_t:s0      root    root     1024 Nov 30 20:36 boot
drwxr-xr-x.  10 system_u:object_r:cgroup_t:s0    root    root     4096 Nov 30 20:59 cgroup
drwxr-xr-x.  19 system_u:object_r:device_t:s0    root    root     3980 Jan  5 17:08 dev
drwxr-xr-x. 123 system_u:object_r:etc_t:s0       root    root    12288 Jan  5 17:08 etc
drwxr-xr-x.   4 system_u:object_r:home_root_t:s0 root    root     4096 Nov 30 21:03 home
dr-xr-xr-x.  12 system_u:object_r:lib_t:s0       root    root     4096 Jan  5 17:04 lib

'ls -lZ' shows another one.
# ls -lZ
dr-xr-xr-x. root    root    system_u:object_r:bin_t:s0       bin
dr-xr-xr-x. root    root    system_u:object_r:boot_t:s0      boot
drwxr-xr-x. root    root    system_u:object_r:cgroup_t:s0    cgroup
drwxr-xr-x. root    root    system_u:object_r:device_t:s0    dev
drwxr-xr-x. root    root    system_u:object_r:etc_t:s0       etc
drwxr-xr-x. root    root    system_u:object_r:home_root_t:s0 home
dr-xr-xr-x. root    root    system_u:object_r:lib_t:s0       lib

Expected results:
We can get same results even if the order of options is changed.

Additional info:
In coreutils/src/ls.c patched with SELinux.patch,
1696         case 'l':
1697           format = long_format;
1698           break;

1940         case 'Z':
1941           print_scontext = 1;
1942     format = security_format;
1943           break;

If 'Z' option precedes 'l', the variant 'format' is set to 'long_format'. But 'l' option precedes 'Z', it's set to 'security_format'.
