: I think you have a couple of problems here. First, you'll have to
: normalize the scores to get *any* of them to be the same. Since
: the scores are a float, very few of them will be exactly the same.
it's not as rare as it seems, with lengthNorm byte encoding and low tf
values it can happen quite a bit -- with a custom Siilarity you can *make*
it happen a lot.

based on the example you gave, it sounds like you don't really want to
sort on score at all ... you just want a randomized sort after sorting on
the priority field.
Solr has a "RandomSortField" which contains a "RandomSort" class that
don't think has any deep Solr dependencies ... it works by using the
"field name" arg as a seed for randomizing the order of results, so you
can iterate/paginate over a consistent "random" ordering as long as you keep
resuing hte same name ... pick a differnet name everytime (use a counter,
or a random number) and you'll get a different order.
you could use that as a secondary sort after your priority field (or a
tertiary sort after score)
