Is your $data hash or array? The source for HTML::Pager does: 
  # fill in the template  
  if ($args_type eq 'ARRAY') {
    # handle array case
    my @pager_list;
    if (defined($self->{column_names})) {
      my %row;
      my $x = 0;
      foreach my $col_name (@{$self->{column_names}}) {
        $row{"PAGER_DATA_COL_$x"} = "<B>$col_name</B>";
        $x++;
      }
      push(@pager_list, \%row);
    }

    foreach my $rowRef (@{$self->{data}}) {
      my %row;
      my $x = 0;
      foreach my $value (@{$rowRef}) {
        $value = '' unless (defined($value));
        $row{"PAGER_DATA_COL_$x"} = $value;
        $x++;
      }
      if ($x) {
        push(@pager_list, \%row);
      }
    }
    $template->param('PAGER_DATA_LIST', \@pager_list);
  } else {
    # handle the hash case
    $template->param(PAGER_DATA_LIST => $self->{data});
  }

which at first glance appears to ignore $self->{column_names} in the hash case.
