In the script there is a .sof file referenced. Additionally, if I check the JTAG chain of our hardware, I only see the Cyclone I FPGA, but no flash.

Flash will not show up in the JTAG chain. Most likely the Cyclone I is configured from EPCS. Did you look at the schematic for the board?

So I already thought to myself that the FPGA will be configured as some kind of flash programmer by the nios2-flash-programmer.exe. Then, the flash image will be programmed into the flash device by via the FPGA. This sound pretty much like I program the Cyclone III config device with my .jic file.

Yes, exactly. If you look at the schematic and see an EPCS flash, then you can just program it using a .jic. Once you confirm that works, you can use whatever file the command-line tool expects. For example, I believe you can save the JTAG chain from the programmer GUI, and then use that from the command-line.
