Are you asking the difference between:

sort -t , -k 1n
sort -t ',' -k 1n

If so, there's no difference.  The shell strips the '' quoting around ,
before invoking sort, so argv[] is the same in either spelling from the
shell.

But that has nothing to do with the bug report, where the answer is that
the caller should have been using:

sort -t , -k 1,1n

or

LC_ALL=C sort -t , -k 1n

or the combination:

LC_ALL=C sort -t , -k 1,1n
