This is an illustration of why the expression SRF API isn't very useful for returning composite types ;) The number is actually a pointer to the result row. There is no way under the expression API to get at the individual columns directly. If you're really curious, see contrib/dblink in 7.2.x for an example of a (ugly) workaround.
