Is this the correct behavior?

irb(main):001:0> Integer('0123')
=> 83

Shouldn't the return value be 123?

No, 83 would be the expected result, just as if you specified 0123 in ruby code. Kernel#Integer treats a leading 0 to mean octal, leading 0x to mean hexidecimal, and leading 0b to mean binary, just as ruby itself does.

Try Integer('0123', 10).
