$spam_score_int is defined whenever your Exim is built with
scanning included. It will expand to an empty string if it
has not been set.

Poor wording in the docs, I'm afraid. It actually tests for
a non/empty post-expansion string; and would be the right thing to use
here. Use two condition= lines, with the def: test first.
