map {s#|#\\|#s; $_} @results

I hope you don't have any other uses for @results as you've modified it in-place.

Perl doesn't have a great idiom for this. This type of mistake and several others are so common that I really think Perl should have a 'filter' keyword.

And thanks(++) for bringing up the important point about escaping regular expression metacharacters and prompting diotalevi's reply (which is what I'd use).
