Haven't figured out how to do it with the conditions field, but by rplacing the DZE_DEPLOYABLES_CONFIG with the bellow you'll be able to set the config for each humanity level.
private['_hum'];
_hum=(player getVariable["humanity",0]);
if(_hum > 5000) then {
DZE_DEPLOYABLES_CONFIG = [
["ItemToolbox",[0,6,1],5,0.1,false,false,false,false,false,true,true,["Nissan_Red_DZE4"],[],[],"true"]
];
} else {
DZE_DEPLOYABLES_CONFIG = [
["ItemToolbox",[0,6,1],5,0.1,false,false,false,false,false,true,true,["MMT_USMC"],[],[],"true"]
];
}
