Without seeing your input data, this is hard to tell. Your code seems to do some wonky CSV parsing here:

                my @pinWords = ();
                if($line =~ m/.*?,.*?,.*/){
                    @pinWords = split(',',$line);
                }
                elsif($line =~ m/.*?;.*?;.*/){
                    @pinWords = split(';',$line);    
                }

and then you write that value directly into the hash:

...
               $pin =~ s/^\s*|\s*$//g;    #To remove all leading and t
+railing blanks
...
                    $pinList{$pin} = [$pinMaxSDV,$pinMinSDV];

So my guess is that sometimes your CSV input data has double quotes around the pin and sometimes it does not.

See Text::CSV_XS for CSV parsing.
