winning/losing streak without dates in order

I have a tough one here:

I need to calculated a longest ever winning streak and current winning streak for a largest set of data.

The data is set up as follows:

Column A [B C D] [E F G] [H I J]
List of teams each brack represents a team
(can't be sorted) B / E / H all would be dates
C / F / I all would be W/L
D / G / J all would be scores

I need to determine the longest ever winning streak and current winning streak for each [bracketed] team. The problem is column A is fixed and can't be sorted, therefore the dates are out of order.

Please let me know if this is impossible.

Thanx
