This is a very interesting application of WolframAlpha but it appears to be purely luck when "success" was the result. Using things such as "2nd item in a..." or "7th digit in..." work in a lot of cases but lets talk about a few.
"2nd fruit in bear apple goat orange" would result in apple because it is looking for second in a list and neglects context of fruit.
"7th digit in abc123def456ghi789 " would result in d when it should be 7. Again not understanding context and merely looking at logical construction.
