Bash sorts filenames lexically when using globs.

for file in *

does what you want without needing to use the sort utility and without
involving ls. It works even if filenames contain spaces or newlines - just
make sure you quote the variable when you're using its value

You don't need command substitution as a result, but when you do always use
$() and never use backticks.
