No experience with what you are asking about but if you have lat and lon you could use a location service to i.e. generate a Country or City for which you then add points accordingly.
Would the location be used for content (posts/pages etc) or for users?
Lat/lon are numbers so, if the meta is between. This range of numbers, then award bonus points.. the locations are from players posting in specified locations like a geocache game. Truth is, i would love to award points based on combination of category, tags, if photo included, time & location.. so the playrr must match all criteria.

Sounds like we would need to build some custom logic that gives points. i.e.:
IF post have the tags: yellow, bike
AND in category: activities
AND has feature image
award x points.
I know the wordpress mobile app has an option for geotag too, but i dont know what it does with this info or how to utilize it in my rss
How to utilize that WordPress mobile app with geotags I can not help you with. Try the mobile apps support forum for that question.
