Not so elegantly.

Map doesn't come in handy here because the string would get converted
to a 0. What you can do is hold the split inside a temporary variable
and construct another array, as such:

arr = "3:43;SD,2:65;SD,3:50;Inc".split(/,/).map do |i|
	t = i.split(/:|;/)
	t[0..1].map { |j| j.to_i } << t[2]

	### If you're using Rails you can use Symbol#to_proc to simplify the code
	# t[0..1].map(&:to_i) << t[2]

	### or something very simple, if a tiny bit repetitive:
	# [t[0].to_i, t[1].to_i, t[2]]
end
=> [[3, 43, "SD"], [2, 65, "SD"], [3, 50, "Inc"]]
