You'll need SQLite Editor from play store to find it on your phone, or you can flash it via recovery using the sqlite binary, a shell script, and a SQL query.
I'm actually wanting to do this in my ROM also but haven't looked into it much yet, but here's the SQL query that I currently have (untested, may need work as I'm a bit rusty with SQL queries).
UPDATE system SET value='0.85' WHERE name='font_scale';
I'm sure there's a place in the ROM, I've just not found it yet. I've seen ROMs on other devices in the past with font scale set low.
