If you run it standalone with warnings enabled, you get this:

Variable "$val" will not stay shared at a.pl line 6.

Which is pretty much what is happening. There's plenty written about
this on the web. This has a good summary as well as solutions:

http://perl.com/pub/a/2002/05/07/mod_perl.html

In particular, if you "use diagnostics" it suggests an anonymous sub
will deal with it.

Hope this helps,

---- a.pl ----
use warnings;
use diagnostics;

sub test
{
    my $val;

    sub init {
        $val = $_[0];
        print( "1: $_[0] " . \$val . "\n");
    }

    init(12);
    print("2: $val " . \$val . "\n");

}

test;
test;
