This should work just fine. It sounds like a quote is being dropped
somewhere...
I just tested it here and it works just fine.

Again, what it should do, both 't' and 'f' are non-zero as far as Perl is
concerned.

Your first choice (value eq 't') should do the trick. However, it sounds
like there is another problem interfering with it. Could we see the code?
