SunOS and Solaris were seperate creatures up until about Solaris 2.4 and
SunOS 5.4 when they began merging the two into one entity.
As for the numbering scheme that is definitely weird. It's advertised as
Solaris 7, yet in the code it comes up as 2.7. Guess their marketing dept.
had an afterthought about it.

 Solaris is officially SunOS. 
I wasn't sure what was meant, but what you describe is what I usually
assume as well (though SunOS != Solaris, according to Sun -- they seem to
have changed their marketing position recently, to say nothing of the
numbering scheme).
