Looking at the code in src/glpkapi09.c and glpapi13.c the documentation
is wrong.
The problem accessible in the MIP callback is the presolved and scaled
problem. So if you have a heuristic solution expressed in your original
variables you should switch off presolving and scaling.
Perhaps it would be a good idea to make the presolving and
scaling transformation available to the user program.
It could just be a matter of documentation.
The information must already be somewhere,
otherwise glpsol could not invert it.
