Indeed, /first/secondScoreIsAbsolute, like any option that goes with a specific engine, (e.g. whether it has own book, is UCI etc.) are not persistent, (i.e. not saved in the settings file). Because the engine name itself is also not persistent, so that next time you might run with a different engine, that would not need the option.
The idea of such options is to use them on the 'engine line' in the engine list, from which engines are selected. You can use the Engine -> Edit Engine List option to add such options to the engines for which they are needed. Like
"Crafty" -fcp "crafty.exe" -fd "../Crafty" -firstScoreIsAbsolute true
The engine list is persistent, but the option will only be invoked when you select Crafty.
