In Telligent 7.0, we introduced a new scoring system. Along with that we've created a few scores, primarily around quality and abuse. Our quality scores (for content and authors) are normalized and are a relative score used for comparative purposes only. Displaying the raw Author Quality score isn't recommended as there's no meaning to the values (for ex. User A = 0.103486, User B = 0.087643, User C = 0.002345). You can use the Member List widget to display the "Top Quality Authors" for a group, and this will rank the group members based on their author quality score in the group.
The existing points system is a point aggregator which primarily concerns itself with participation. There is no out-of-the-box way to merge the two systems at this time. You could create your own custom score that combines the two and then choose to rank members according to that new score value. This would require custom development. For example, you could configure the points system to only accrue points for participation type activities and then take that value and multiply it by the user's Author Quality score. This would, in effect, recognize the users who create the most content of the highest quality.
