awk is not strongly typed ... variables are what you coerce them into being.
In the first example you assigned "a" pure numeric values.
In the second example you assigned "a" all strings (each value contains 2
spaces)
change your first example to this:

awk '{a[NR]=$0 ""}END{ asort(a);for(;i++<NR;){ print a[i] }}' f

and it will string sort too
