It is simple, but it doesn't quite match the sample results. This approach ignores elements in %hash that are not in @mips, whereas the original example removed them.

Here's a small rework that fixes it: 
my %newhash = ();

for (@mips) {
   $newhash{$_} = $hash{$_} || 999;
}

%hash = %newhash;

lestrrat's solution is much more fun to look at, though.
