You need to capture the results returned from your subroutines 
my $av = aver();
my $min = min();

Then just make sure to return a value in your min subroutine. 
sub min {
    my @num = @_;
    my $min;
    ...
    return $min;
}

Finally, you would be much better off if you had use strict at the beginning of your code.
