Presedence. "@_ is always evaluated to a true" - No, "@lexlist = @_" is.

I think these braces are in the right place:

my @lexlist = @_ or sort keys %lexicon; # read as (my @lexlist = @_) or (sort keys %lexicon);
What you want is:
my @lexlist = @_ || sort keys %lexicon; # read as my @lexlist = (@_ || sort keys %lexicon);
Or use braces:
my @lexlist = (@_ or sort keys %lexicon);
Hopefully the braces make it a little more readable :) or, and & not have much lower presedence than || && and !

In my experience, to avoid such confusion, I avoid the English versions...

Update: see below :) /me eats humble pie and revisits old scripts to see why this has never caused me a problem b4...
