"Our DNS is working correctly.."

Are you sure?
I ran your script on my local machine against 'google.com', and got the following: 

time perl resolver.pl
1: 64.233.187.99 (record type A)
2: 64.233.167.99 (record type A)
3: 72.14.207.99 (record type A)

real    0m0.661s
user    0m0.530s
sys     0m0.040s

I tried it against a few other domains with similar results. Are you sure you don't have some local DNS weirdness going on?

What happens when you do manual lookups against your local domain?

Cheers,
Darren :)
