You are not checking if your match is successfull. Only a successfull match sets $1 (and the other variables).

foreach my $try (@array2) {
  $try =~ /^(.*),"(.*)",(.*),(.*),"(.*)"/s
      or die "Malformed input data: >>$try<<";

  ...
};

Also consider putting the code you post into <code>...</code> tags, so it can be downloaded and it renders nicely.
