Using * globbing is dangerous with files with names like '-delete'.
I'd recommend to use
find . -mindepth 1 -maxdepth 1 ...
and changing the later substr to strip off the leading './'.

Alternatively to having 2 OR-ed conditions, one could use %y (print file type).

This fails (or gives surprising results) if the first file starts with
a minus; better tell 'ls' that the options end here with '--'.
Finally, if the directory is empty, xargs would still invoke 'ls' once
without an argument; thus use the -r, --no-run-if-empty option.
This makes:
$ find . -mindepth 1 -maxdepth 1 -printf '%y%p\0' \
| gawk 'BEGIN { RS = "\0" };
/^d/ { dir[NR] = substr($0, 4); next; };
{ nondir[NR] = substr($0, 4) };
END { asort(nondir)
asort(dir)
for (l in nondir)
printf("%s\0", nondir[l]);
for (l in dir)
printf("%s\0", dir[l]); }' \
| xargs -r0 ls -dU --color=auto --
Have a nice day,
