It would be convenient if we could distinguish between "+50%" and
"50%", but you can't.

On the other hand, we could go the calc route and require a space, so
that "adjust-alpha(red, 50%)" would set the alpha to 50%, but
"adjust-alpha(red, + 50%)" would make the alpha 50% larger.  Seems
kinda clumsy, though.
