If a Scrolled widget is created, it will not allow it to grow vertically
when it's space is changed.
Try this:
perl -e 'use Tk; $a=new MainWindow;
$b=$a->Scrolled("Text",-scrollbars=>"e")->pack(-side=>"top",-fill=>"both",-expand=>0);
MainLoop();'
Then manually resize the window in both X and Y directions. The
scrolled Text region will grow horizontally but not vertically. Text
grows fine on its own, but other widgets behave the same when managed
this way so it's something do do with "Scrolled". Putting the scrollbar
at "n" does not change anything.

As Slaven has commented this is not actually a problem with Tk::Scrolled.
Investigation shows that what you are expecting is the behaviour when you
use expand=>1.
Reading the section "Expanding the Allocation Rectangle" in Chapter 2 of
"Mastering Perl/Tk" (page 29 in my edition) explains what is happening. When
the window is resized the *widget* size changes, but, unless expand is true
then the *Allocation Rectangle* is fixed in one axis, try using
-side=>"left" instead of "top" to see what happens.
It is possible that this is a bug in Tk, however too many applications
probably rely on the behaviour for the Tk maintainers to want to change it.
Bug closed - If you want to take this further then please talk with the
developers of Tk.
