Use a portal with only 10 rows and specify the needed sort order either in the relationship or portal setup.
Perform a find to find your records
Then use Omit Multiple records to omit all but the first 10 records.
But those "summary totals" may be a significant complicating factor. What records in what table would provide the data for those summary totals?
If all the data is in a single table, you aren't limiting your view to 10 records, but 10 groups of records as determiened by a summary value in a summary field. This can be done, but it's a much more complex undertaking. If that's what you are dealing with, please describe what you are doing in more detail.
