Any idea why the normal version yields lower scores than the unlimited vision on the iPhone 12, while there is no such difference on previous iPhones? I

The "regular" benchmark on iOS is limited by the display refresh rate. So if your device can render faster than 60 frames per second (the iPhone 12 can), it's score will be artificially lowered. The "ultimate" version uses an off-screen frame buffer, so it forces the GPU to draw as fast as it can.

Of course there would also be such difference on previous iPhones too. It illeminates a number of variables to level out the playing field (vertical sync, display resolution scaling and other operating system factors affecting the result), to get a closer chip to chip comparison.

 
Well, that's the thing. There is no such difference on previous iPhones (nor on android phones for that matter).
Look at the second and third tables of this review:

The differences on other phones are smaller to non-existent because they are generally unable to draw faster than the screen refresh rate :) My iPhone 11 for example manages to just barely touch 60 fps in some scenes, but the iPhone 12 goes up to 70 fps. I think that @Significant1 is correct that there might be additional factors (like the overhead in actually displaying the image), but they are all very small compared to the forced vsync.

Ok, I don't know then. There must be bottleneck on 12/12 pro pushing the graphics to the screen, which the other don't have. Leman's suggestion is good, but the average fps in the tables are well below 60 and strange 11 pro fairs better 🤔. Anyhow I am not a gamer or expert in this field.

But still, the iPhone 12 should be faster than the iPhone 11 in normal mode. If frame rate was caped at 60 fps more often on the A14, it must be higher overall. We see the opposite.
 
Not the stress test, but i am getting these results. Battery % does play quite a big role here

This could be some bug in the Metal driver of the A14.
🤷‍♂️ but the delta for 11 Pro Max is bigger in the result browser of the app. normal 7033 vs unlimited 7967. The difference is your link had a normal score of 7709, while about the same for unlimited.
