The latter.

Who said that `sort' understands \t as a TAB?  This would probably
work in a Unix shell, since the shell itself converts \t to a TAB, but
DOS shells don't do that.  You need to actually press a TAB (and
enclose it in quotes) to make this work.  When I did that, your
example worked for me.

Btw, I don't even understand why did you need to use the -t switch:
TAB is considered a field separator by default, since it is a
whitespace character (see the `sort' docs).
