Not sure where you are having a problem - if you can create a simple polygon with a few vertices it is easy to add as many vertices as you like: 
my $shp_writer = Geo::Shapefile::Writer->new( $name, 'POLYGON', @attr_
+descriptions );

my $shape = [
    [86.925, 27.988],
    [86.5278, 27.744],
    [86.43, 27.365],
    # ...many more vertices
];

$shp_writer->add_shape( $shape, @attributes );

    Because POLYGON supports multi-part polygons you have to put each part in an array reference too. 

      my $pt1     = [ $x, $y ];
  my $part1   = [ $pt1, $pt2, ...];
  my $polygon = [ $part1, $part2, ...];
