There are preview builds of Geekbench that are native RISC-V.
I highly recommend it, most incisive RISC-V article I've read.
Geekbench does indeed not support the Vector extension, and thus yields very poor results on RISC-V.
RISC-V does indeed not have pipeline reordering.
The Geekbench score thing is a strawman invented to distract from that, no one has mentioned Geekbench except the people arguing it doesn't matter. Everyone agrees, it doesn't matter. So why pound the table about it?
