It also doesn't survive across conversions. There is a keywords field in EXIF data which should be used for tags. The field is just a comma separated list of tags, keywords etc. Not sure what photo management tools use this field or can search on this field. You could always play with a package called exiftool which is cross platform but command line driven. Very powerful, though.
