I guess you realised that, when on a website, you click on the \'like\' button -with counter- it normally updates one like by one like in the first ones. Until it reaches 1000 \
You can query the exact 'like' count yourself and create a custom counter.
example in PHP
$url = 'http://example.com';
$facebook_data = json_decode(file_get_contents("http://api.facebook.com/method/fql.query?query=select%20total_count,commentsbox_count%20from%20link_stat%20where%20url='{$url}'&format=json"));
echo $facebook_data[0]->total_count;
You can see a working example of this on http://askdavid.com
You could set layout style to standard instead of the box count. But the way box count works is that it displays a rounded number and that isn't currently configurable. You could log a feature request on their bug tracker tool.
