I appreciate the clearly-stated question about print, and the very informative replies it inspired, but I had to wonder about this bit in the OP:
I'm modifying a program which uses IPC::Open3::open3 to fire up mysql and query the database.

I wonder if it might be easier to just use DBI (which, if told to connect to a mysql database, will automatically use DBD::mysql).
