[0.15.15] Research incorrectly ordered

[Laar]

After gaining a better understanding of the research ordering (see this report) I still think there is a bug.

In the screenshot below there are I think 3 errors. Both "Cannon shell damage 6" (position 2) and "Grenade damage 7" (position 4) cost 2000 of their science packs, though the other technologies, up till position 9, require the same science packs but only 1000. Similarly, "Mining productivity 16" costs 1500 packs and is placed before "Worker robot speed 6" costing the same science packs but only 1000.

What I expected was that the most expensive research was placed last in the list. First sorting by the type of science packs needed, then by the number of packs needed (as in the number next to the list) as explained in this post by Rseding91. Thus the order would be (last to first) "Cannon shell damage 6" and "Grenade damage 7" last (only ones costing 2000), then "Mining productivity 16" (costing 1500) followed by all other researchable techs (all costing 1000).

It is ordered correctly, expensiveness does not relate to the number of packs required, just the type of science pack it needs,
If all are the same science packs, they are ordered by their order defined by prototype
