At a glance, the difference there is the type of command.  For both MGED and Archer, some commands are built-in registered from C (most of the editing commands like 'in' and 'make') while others are implemented in Tcl (such as '?' and 'reid').

If a pure-Tcl command fails, it's usually a path problem of some sort.  That could be a compile-time or run-time path issue but is almost always related to the Tcl auto_path.  It's usually seen when there are partial installs, multiple versions of Tcl, running without installation, etc, as you noted with your follow-up "fix".
