Is this too naive/non-Rubyish for what you had in mind? I just moved
the .to_i; it seems to work...

===========
def expect(msg, expected_value)
  puts "#{msg}#{expected_value}:"
  loop do
    actual_value = gets.chomp
    return actual_value if actual_value.to_i == expected_value
    puts "Sorry, expected #{expected_value} but got #{actual_value}"
  end 
end

expect('We want ', 98)
===========

Thank you again
