Ruby is my language of choice, but I have done some work in Python.

For all the things you listed, there are libraries in both languages that
are probably as good as each other.

Python has lxml, which is as good as Ruby's Nokogiri for XML stuff. Python
has Sunburnt for Solr stuff, although I do really like Sunspot (and Tire
for ElasticSearch is even better).  Both Python and Ruby have mechanize for
screen scraping,  which was actually based off a Perl's WWW::Mechanize

I will say that  while Ruby has more web application building tools, I
think Python is still more popular with science-y type people. Python seems
to be what all "Programming 101 for Non-CS Students" classes use now, so I
think Python has more data processing/science libraries, especially for
things like  Natural Language Processing and statistics. I went to a
Semantic Web workshop and everyone was using Python or Java, although there
are some Ruby libraries out there...

That said, JRuby has really come a long way in the past year, so now it's
easier to use the bad-ass Java libraries ( like Marc4j, CoreNLP, and Java's
XML libraries)   without actually having to put up with all the crap Java
makes you submit to.

In terms of speed/performance both Ruby and Python are equally terrible.

I guess I'd just recommend instead of learning both languages, I would push
myself to learn one really really well. That was something I learned the
hard way when I was younger...always learning a language just well enough
to get comfortable then getting bored and trying something else.

good luck!
