Unless the content for both the docs is exactly the same it is highly
unlikely that you will get the same score for the docs under different
querying conditions. What you saw in the first case may have been a happy
coincidence.
Other than that it is very difficult to say why the scoring is different
without getting a look at the actual query and the doc content.

If you still wish to dig deeper, try to understand how solr actually scores
documents that match your query. It takes into account a variety of factors
to compute the cosine similarity to find the best match.
You can find this formula and a decent explanation for it in the book solr
in action or online in the lucene docs:
