I believe they try to put newer content first in order to make a more fair distribution of views. If you order results by popularity on yt, you will see that it uses just an "order by view count desc" (no relationship with like/dislike ratio), which is bad because it keeps popular some not so good quality videos published on first yt years.
I know it's not google proper, but I'd guess a significant number of their searches are specific to youtube.
