Consider using Getopt::Long instead of hand-rolling your option parsing. Getopt::Long can also set up your callbacks but will handle many more features:

use Getopt::Long qw(:config pass_through);
my $run;
GetOptions(
    'x|run-using-system'   => sub { $run = \&system },
    'X|run-using-mysystem' => sub { $run = \&mysystem },
);
$run->(@ARGV);
