Your post is a little bit difficult to read because "$_2 vs $_->2" is rendered a bit confusingly without  <code> tags. Please see Writeup Formatting Tips and Markup in the Monastery. You've already employed code-tags to good effect in your OP; you only need to be more thorough in their use.

As an aside: Do you understand the difference between $_[2] and $_->[2]?

And please do read and follow the principles discussed in the SSCCE article.
