Since you obviously already has solved the problem, I guess you're mostly after other ways to do it just out of novelty or something. But here's another way, at least:

my @numlist = (1,2,3,4,5);
if (join (",", @numlist ) eq join (",", (1..$#numlist+1))) {
       print "correct";
} else {
       print "incorrect";
}

Or more onelinerish:

print ( (join (",", @numlist) eq join (",", (1..$#numlist+1))) ? "corr
+ect" : "incorrect" );

Seems like Array::Compare could be a good place to go too.
