There's a few odd things here, looking at your explains output:
First search, first result:
6.357613 = (MATCH) weight(description:jackshaft in 3339)
[DefaultSimilarity], result of:
6.357613 = fieldWeight in 3339, product of:
1.0 = tf(freq=1.0), with freq of:
1.0 = termFreq=1.0
10.172181 = idf(docFreq=4, maxDocs=48128)
0.625 = fieldNorm(doc=3339)
First result, second search:
6.173014 = (MATCH) weight(description:jackshaft in 25367)
[DefaultSimilarity], result of:
6.173014 = score(doc=25367,freq=1.0 = termFreq=1.0), product of:
0.99999994 = queryWeight, product of:
9.876823 = idf(docFreq=4, maxDocs=35820)
0.101247124 = queryNorm
6.1730146 = fieldWeight in 25367, product of:
1.0 = tf(freq=1.0), with freq of:
1.0 = termFreq=1.0
9.876823 = idf(docFreq=4, maxDocs=35820)
0.625 = fieldNorm(doc=25367)
Firstly, you are getting different docIDs (3339 vs 25367), but that can
be explained by merges changing the order of documents in the index.
Then, you have different maxDocs, which could also be due to different
merging between your replicas - I'd suggest you compare your numDocs for
each replica and see if it is the same.
And finally, and most weirdly, you have two different scoring algorithms
being used between your replicas. One has a query normalization factor,
whereas the other doesn't, which I cannot explain. Between maxDocs and
queryNorm, you are getting ever so slightly different scores which is
causing your order changing.
The maxDocs issue you could potentially mitigate by using the
distributed IDF functionality that was added to Solr not that long ago,
although I haven't myself used it. This would make each replica use the
same statistics when calculating scores.
The queryNorm present in one but not the other I cannot explain.
