Well, there is perhaps a far more attractive option;
Drop the stuff you don't want (the type) by setting it to the same value everywhere, then make use of the stats max() function. You may first need to replace the string 'null' with a real NULL value, if that is what you have. Or perhaps not. At least in my test you don't
your search | eval type = "Combined" | stats max(*) by _time
This should look something like;
2014-09-09 05:57:58, KQ25B6P, 7.7.1, CommandPost+, 4, 70701, Combined, 1401, 6432, 1234, 3424, 7663, 2342, null, null, 8787, 1461, 6735, 8101, 3869, 20166, null, null, null, null, null, null, null, 0, 0, 0, 0, null, null, null, null, null, null, null, null, null, 5435, 123, 0, 6676, null, null, null, null, null, 0
i.e. if there is a field that does not have a value in either of the events, the combined event will still have 'null'. Otherwise, the highest value will take that place.
For presentation purposes you might then want play with fields, replace, table, or rename etc.
Hope this helps,
K
