The following line, in your first example, will result in nothing
more than an entry in your error.log file:

    my $desc = $Tag->item-description;

As will the following line, in your second example:

    my $desc = $Tag->scratch(kotest);

The error.log entries should have explained the problems, or at the
very least, alerted you to the fact that the problems exist.

You could access the scratchpad variable, in your second example,
using $Scratch->{kotest}.  Well, you could if you'd set the variable
correctly in the first place. :-)

Alternatively, you could rewrite your Perl as follows:

    [item-calc]
        my $desc = q{[item-description]};
        return "$desc<br>";
    [/item-calc]
