Other people have commented on other frameworks etc for assessing value,
but informally, I've found myself focusing on three criteria when pondering
priorities for government data release:

1. Uniqueness: to what extent are there no other sources of this
information? A council's collection of street information is valuable but
there's a lot of overlap with OpenStreetMap, for instance. But no one else
could have the garbage collection zone boundaries.
2. Maintenance. Datasets age pretty quickly, and a dataset that's more than
a year out of date seems to go downhill in value pretty fast.
3. Reusability: was the data being collected with a general purpose in
mind, or are there limitations due to the original purpose for which it was
collected (eg, lack of comprehensiveness, idiosyncratic groupings,
jurisdictional filtering...)
