the MPS files in http://plato.asu.edu/ftp/lptestset/network/
contain keyword OBJSENSE, which can take values MIN and MAX.
Could you, please, consider adding support for this keyword in GLPK.
See "Objective Sense and Name in MPS Files" in
GLPK does not support the keyword currently. It will default to
minimization. Please, remove the keyword OBJSENSE and the value line
