A new language can be defined that sets these entries:

\documentclass{article}
\usepackage{listings}
\lstdefinelanguage{PodPerl}[]{Perl}{podcomment,printpod}[pod]

\begin{document}
\begin{lstlisting}[language=PodPerl]
#!/usr/bin/env perl
use strict;
$^W=1;

my $title = "Hello World";
print $title;
1;

__DATA__

=head1 NAME

My title with ' as single quote.
...

\end{lstlisting}
\end{document}

Also the example above shows the problem.
Perhaps a bug?

If you have a POD section without Perl code, you could use
  deletestring=[b]", deletestring=[b]'
