Half Reactions with the Electron Transport Chain

The half reactions for a newly discovered electron transport chain in an alien species are given in the Table.  From their E0’ values what would you guess is their order in the chain?  What would you need to know before you were more certain of their order.
Table: Standard redox potentials for electron carriers in the alien respiratory chain
Half reaction                                                                                   E0’ (V)
Boba Fett Ubiquinone  + 2 H+ +  2e- → Boba Fett ubiquinol                    0.027
Cytochrome Zaphod (Fe3+) + e-   → cytochrome Zaphod (Fe2+)       0.085
Cytochrome Audrey II (Fe3+) + e-   → cytochrome Audrey II (Fe2+)   0.33
Cytochrome ALF (Fe3+) + e-   → cytochrome ALF (Fe2+)                   0.37
Cytochrome Na’Vi (Fe3+) + e-   → cytochrome Na’vi (Fe2+)                   0.40

I said that the order is opposite what is listed (from cytochrome-->Boba Fett Ubiquinine)
