Score field statistics

In our application we are using Solr 4.1.
And we wanna filter results by score relevance.
I had the idea to use statistic data (i.e. standard deviation, mean) for
score field. 
Is it exists workaround of using "…stats=true&stats.field=score..." ?

Thanks in advance

Sorry, didn't catch the part where you also wanted statistics from the
StatsComponent. I do not think that it is possible to do this for
pseudo fields like score. You would have to collect the scores, and
calculate statistics yourselves.

Thanks for response,

But problem is that "SolrException: undefined field: score" appears after
trying to get stats for score pseudo field.

Sincerely, 
Alex

Even simpler: You can just add &fl=*,score to get the score returned
in the search results along with all other fields. Please see
