The line if [ $SCORE -lt 0 -a $SCORE -gt 100 ]; then is looking to compare integers. You are giving it letter, which it cannot handle. You would be better to put the quit-test before it.
That said, you also don't check that someone enters the value b or Hello world! in there.
Is this a homework exercise?

xml::filter::buffertext
BufferText(3) User Contributed Perl Documentation BufferText(3)
NAME
XML::Filter::BufferText - Filter to put all characters() in one event
SYNOPSIS
my $h = SomeHandler->new;
my $f = XML::Filter::BufferText->new( Handler => $h );
my $p = SomeParser->new( Handler => $f );
$p->parse;
DESCRIPTION
This is a very simple filter. One common cause of grief (and programmer error) is that XML parsers aren't required to provide character
events in one chunk. They can, but are not forced to, and most don't. This filter does the trivial but oft-repeated task of putting all
characters into a single event.
Note that this won't help you cases such as:
<foo> blah <!-- comment --> phubar </foo>
In the above case, given the interleaving comment, there will be two "character()" events. This may be worked around in the future if there
is demand for it.
An interesting way to use this filter, instead of telling users to use it, is to return it from your handler's constructor, already
configured and all. That'll make the buffering totally transparent to them ("XML::SAX::Writer" does that).
