Thanks for the report however this is not a bug and works how described. Your technologies have different costs - one takes 100 science packs and one takes 80. The one that takes 80 comes first because it takes less packs.

Technologies are ordered:

Hi, after checking that it's still not possible in 2.1, I am again asking for this feature since the feasibility of it might have changed since 2.0, and because I think the request is still relevant.
