Actually, this seems like a misunderstanding on your part as to how sort
works.

That says to use the string from the third field to the end of the line as
the sort key.  You probably meant:

sort -t\<tab> -k3,3 ts.txt

which says to use ONLY the third field as the sort key.  Likewise for your
other examples.
