Hi,

Assessing alignment quality is an active area of research. I suggest you search the web and the literature for possible tools and try them on your alignment to assess which will work for your case. See:

https://www.google.com/search?q=alignment+quality+score
http://europepmc.org/search?query=multiple%20alignment%20quality%20score

All the best,

Note that later on I found the following page which describes some methods for scoring a multiple alignment

-scoring functions
--minimum entropy
--sum of pairs
