You might be better on the Open Source Archaeology list :)
Speaking as a non-archaeologist working in archaeology, precision of millimetre is nonsense, achieved or not, as (a) the things they are recording were not built to that precision, nor in many built-structure cases even designed and (b) stuff in the ground for that long has moved...
CAD doesn't make sense, even though commonly used, as CAD (as any engineer will tell you) is a design tool, not a recording tool. GIS makes much more sense for the majority of recording as the data will require much analysis to be really useful, and a map can be later produced via Inkscape. We have a member of staff who's developed a nice survey workflow using QGIS and Inkscape.
