Are Memory Maps sorted?

Are Memory Maps sorted?

Well, just as in the Subject, can we assume that Grub2 Memory Maps that the
OS finds in the Tags are always sorted from the lowest base address to the
highest?

Can we also assume that they do not overlap?

I already noticed that on many (read "all I've been able to test on") PCs
the memory maps will contain holes, zones of memory which use is unknown.
Can this be considered a bug?

Thanks.
