Mutt even considers a line w/o a leading minus sign as the beginning of
the body. I just checked it in mutt, it seems to autoconvert

    X-Torres-Spam-Score: 4.5
    -4.5


to
    X-Torres-Spam-Score: 4.5


    -4.5


And this change is written to the message file! (At least if I use a
local maildir storage).

Seing this, there is no bug in Exim. Exim does just what you told it to
do. As indicated by the filter test output.

Yes, I just wanted to check if your filter test output does not differ
from that one I get.

Using 'headers add "x-torres-spam-score: $h_x-spam-score"' IS wrong.
For that reason I proposed the solution using reduce{}, that does
basically the same as the sg{} solution from Marc. Both may be
considered ugly, but the reduce{} at least treats the $h_x-spam-score
as what it is - a '\n' delimted LIST of header values.
