rlm_perl truncating some attributes in 3.0.1

I'm trying to upgrade our 2.2.1 based servers to 3.0.1, but it appears that rlm_perl is truncating some attributes. Specifically Calling-Station-Id, User-Name and User-Password. Here is the debug output from the server: http://pastebin.com/GYpBS59L And here is the rlm_perl script that currently works under 2.2.1 but appears to be receiving truncated %RAD_REQUEST attributes: http://pastebin.com/auKspQcU Is this normal behavior that can be overridden at script definition time? Thanks!
