Query plan utilization vs CPU time...

I was tuning a query testing out SARG with these two queries:

select col1 from table1 (nolock) where col1 like '#,%ABC%' or col1 like 'BC,%ABC%'
select col1 from table1 (nolock) where col1 like '%ABC%'

I flushed out the cache, added an index to col1, then ran those two together. Provided below are the actual query plan and stat time:

Query 1: Query cost (relative to the batch): 0%
select col1 from table1 (nolock) where col1 like '#,%ABC%' or col1 like 'BC,%ABC%'
-
SELECT Index Seek
Cost:0% <- [DB1].[dbo].[table1].[Idx..]

Cost: 100%

Query 2: Query cost (relative to the batch): 100%
select col1 from table1 (nolock) where col1 like '%ABC%'
-
SELECT Index Scan
Cost:0% <- [DB1].[dbo].[table1].[Idx..]

Cost: 100%

STAT TIME--

As expected, SARGable Query 1 did a nonclustered index seek and nonSARGable Query 2 did an index scan instead. According to the query plan, Query 1 consumed 0% relative to the batch whereas Query 2 is 100%. When I checked the CPU time, I was a bit confused because Query 1 showed CPU time of 938ms whereas Query 2 showed 515ms. I triple checked and every time I got similar results. I am sure I'm missing something, could someone please tell me what I'm missing? Thanks a bunch!

Btw, I'm using SQL Server 2005. Any suggestion please, even just tell me if this is the right place to post this question. Hope some of you know the answer to this. Thanks!
