The code you show does not do what you think it does. It's declaring a new variable, $number, and then matching the regex against it. Obviously, the regex won't match against an empty string.
I think this code does what you meant to do:
my $got = q!<A HREF="JavaScript:AFunction('AA', 'B','0','Project','113
+')">San Francisco (Manager)!;
$got =~ /'(\d{3})'\)">San Francisco \(Manager\)/;
my $number = $1;
print $number;

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.
