Typically, Google doesn't allow you to geo-target a ccTLD (country specific top level domain). Google assumes that if you register a country specific TLD, you want to rank well in that country. They made an exception for a few ccTLDs including .TV domains a while back, but the .ME domains were not included in that exception.
That has changed as of August 17th. In fact, this blog has a screen shot proving it. But there are other various reports of this actually working. .ME is a natural ccTLD for this exception.
