Are you sure your first conditional is correct? The next loop control statement will go to the next iteration in the current block, which in your case is the immediate foreach loop. Here's an example of some code which works as one would expect

my @l = qw(foo bar baz quux);
foreach (@l) {
    if(index($_, 'a') > -1) {
        next;
    } else {
        print $_, $/;
    }
}

__output__

foo
quux

So we can see that next is being called when $_ contained an 'a'.

Also this might be a better way to loop through your list

&do_something foreach grep { (! conditionA) && conditionB } @tmp;

The grep filters out any elements that don't meet conditionA but do meet conditionB, which is basically what your example loop does.
