How does Commerce select price? [11.5]

Hi!

I found this in our price matrix

Price		Valid				Type
6:20 SEK	today 14:20 -			All Customers
7:00 SEK	12 dec 01:00 - 2030-01-01 01:00	All Customers

So at this moment we have to valid prices, is it that easy that Commerce by default will pick the cheapest one?

Thanks!
