I'm not sure, but I think the better description is that EQ_FUEL_SCOOPS provides
EQ_CARGO_SCOOPS. The EQ_CARGO_SCOOPS doesn't exist as a piece of equipment, but as a function
of the fuel scoops. From the wiki:
"provides" is added in 1.81, and is an array of equipment keys. This allows OXP equipment to provide some functionality from core equipment (or in theory other OXP equipment though this would need to be managed carefully between the OXPs). ...snip... While any string may be added here, only the following items have any in-game effect in the core game:
"EQ_FUEL_SCOOPS": may scoop fuel from a star
"EQ_CARGO_SCOOPS": may scoop cargo. Note: there is no such core game item, but the core fuel scoops have this in their 'provides' list.
Based on this, I don't think you could restrict on "EQ_CARGO_SCOOPS" because it's not a piece of equipment (looking at my save files it's not in the list of installed items). I imagine you could create a piece of kit that only scoops fuel, or that only scoops cargo, and restrict on those equipment keys, but the core fuel scoop does both. Not sure about the order of requirement for missions, though.
