The default for na.last in sort() is NA (unlike sort.list):
sort.list(xd, na.last=NA)
[1] 4 2 3 1 5 6 7
so the answer is correct (and the same as given by 2.7.2).

sort(xd, index=T)$ix
[1] 4 2 3 1 5 6 7
And in my believe it should be
5 2 3 1 6 7 8 4 9
The FAQ asks you to report only things you 'know for certain', not
beliefs.
This was function well in R 2.7.2
Indeed it did and gave the same answer as 2.8.0!
