You can pass an array ref (or even a hash ref) to the -value parameter of CGI::Cookie::new. From the CGI::Cookie documentation:

Create cookies from scratch with the new method. The -name and -value parameters are required. The name must be a scalar value. The value can be a scalar, an array reference, or a hash reference. (At some point in the future cookies will support one of the Perl object serialization protocols for full generality).

So you can set multiple values by doing

my $cookie = new CGI::Cookie( -name => 'ChocolateChip',
                              -value => [ 'Sweet', 'Semi-Sweet', 'Yumm
+y' ]
                            );

If there are multiple values for a cookie, the $cookie->value method will return a list of them (only if it's called in list context, of course).
