awk with fields select?

If i have a log file record.txt, with 10 fields
- First field is datetime
- 7th field is status
- 8th filed is name
- The last field (10th) is epoch time of the first field
Code:
02/17/2012 1:47 PM||||||In Use|chicken||1329515230
02/17/2012 2:53 PM||||||Available|chicken||1329519195
02/17/2012 3:20 PM||||||In Use|cat||1329520802
02/17/2012 3:22 PM||||||In Use|cat||1329520957
02/17/2012 4:18 PM||||||In Use|bear||1329524298
02/23/2012 3:00 PM||||||Available|cat||1330038028

How do i create a new flat file record combine.txt which has 10 new fields
- first field is datetime in epoch "In Use" of the name like chicken
-2nd fields to 10 fields is from "Available" of that name like chicken.
Code:
1329515230||||||Available|chicken||1329519195
1329520802||||||Available|cat||1330038028
1329524298||||||In Use|bear||nowtime


I have problem like we have 2 In Use
Code:
02/17/2012 3:20 PM||||||In Use|cat||1329520802
02/17/2012 3:22 PM||||||In Use|cat||1329520957

How it select and use only the earliest one?
