Ah, I'd misunderstood that it was ignoring the sign and you wanted
to respect it. But you *wanted* to ignore the sign. Thus, you can
omit the optional sign:

:'<,'>s/\d\+/\=submatch(0)+22/g

or move the "\zs" after the optional minus-sign
to get the desired result:

:'<,'>s/property=-\=\zs\d\+/\=submatch(0)+22/g

In both cases, submatch(0) becomes just the number without the sign.

Beware the first one may do odd things in the event you have decimal
numbers in your file, so it would change "11.1" to "33.23" since you
don't anchor the left side.
