Looking at parser_materials.cpp in 3.8, and parstxtr.cpp in 3.7-stable,
the scattering is bound to 1 to SCATTERING_TYPES which is 5.
The warning message is "Unknown atmospheric scattering type.".
The scattering type should appears as XXX in
"scattering { XXX , COLOR "
The restriction 1, 2, or 3 is for the method (of sampling), and should
appears as XXX in
"method XXX"
