The reason the scrollbars 'go crazy' is that you have created one enormously long line. When you add lines and scroll through them, the scrollbars change size accoring to the fraction of lines shown in the window. At the top, you are only showing a part of one line. But in the blank line areas, you are showing many.

To get a better behaved scrollbar, split your input into lines: 

use strict;
use Tk;

my $mw = MainWindow->new();
my $t = $mw->Scrolled('Text',-scrollbars=>'e',-wrap=>"word")->pack;

$t->insert("end"," this is a test\n" x 4000);

MainLoop;
