get member statistics

It shouldn't have to do with account privileges because an operator account should have read-access to the stats. If you didn't have privileges, you would get a runtime exception.

I'd try to turn on the perl SOAP tracing by switching these two lines at the top

use SOAP::Lite + trace => qw(method debug);
use SOAP::Lite;

To

use SOAP::Lite + trace => qw(method debug);
use SOAP::Lite;

Then, you'll get the entire SOAP request/response print out to the console. If you could post the response for the get_statistics() method in question, we can see if the data truly isn't there, or if it's a client processing problem.
