Tried to have a bit of fun with this one:

Input strings are assumed to be of the form "1 2 3" etc.

To save a map call for converting the strings to numbers, I used regular expressions for the partitioning.

Implemented a little helper called tuple2Map for applying a function to both elements of a 2-tuple.

Used an active pattern for deciding which of the sums is greater.

Tests:
