I think you'll find it returns true because 0 == 0.  Perl attempts to 
convert the strings to numbers and fails gracefully, returning 0 if they
don't look like numbers.

In general, if you try and compare strings with a numerical comparison 
operator, then you will get unpredictable results in both TT and Perl (and 
most other programming languages).

So don't do that.  :-)

foo.${'gold-1'}

Very good advice.
