In this case it is because it sees ?' or ?" and interprets that as the character notation (I have no idea what this is called). Putting a backslash in front of the ? fixes the problem locally.

There are a lot of different things that can trip up ruby-mode when inside a string. I tripped on one today with a multiline string with "def" in it:

eval "
  def xxx
    yyy
  end
  "

Notice that tab will indent up to the yyy as if it is actual code, not string content.

BTW, I'm using version 1.0 of ruby-mode.el as supplied in emacs 24.0.50. It may be more up to date in the ruby distro, but afaik, it should be shifting to emacs for distribution.
