There is another way to get to the Word-constants, which in my experience is more stable, when there are many constants, as there indeed are in Word.

I would like to encourage you to try this instead to see if it helps: 
use Win32::Shortcut;
use Win32::OLE qw(in with);
use Win32::OLE::Const; ##=>Changed

my $wdc = Win32::OLE::Const->Load("Microsoft Word"); ##=>Added

my $x = Win32::OLE->GetActiveObject('Word.Application');

# snip

$x->Selection->Delete( {
          Unit=> $wdc->{wdCharacter}, ##=>Changed
          Count=>1
     } );

Searching through some old email conversations with jand, the author/maintainer of Win32::OLE, from 2002 I found this.

Nothing new under the sun, it seems. But the indicated way works.

Notice that your erroneous linenumber is -1 whereas mine is 65535, 16 bit integers or what?
