I have a script log file that looks a bit like this:

2012-9-16
Did something
Did 345 things
Script time: 244 seconds

2012-9-17
Did yet something
Did another thing 23 times
Script time: 352 seconds

2012-9-18
Did something special for 34 seconds 51 times
Did nothing at all
Script time: 122 seconds

I would like to find the largest value of N in the lines Script time: N seconds. However, I need to keep the context, so simply removing all lines that don't contain Script time in them is not a viable solution.

Currently, I am grepping for lines with Script time, then sorting those to find the highest value, then going back to the original file and searching for that value. However, if there is a more straightforward way then I would love to know.

This is on Vim 7.3 on a recent CentOS. I would prefer to remain in VIM if possible. Thanks.
