You would need to effectively subset by checking the date of the most recent (100th) entry returned. Then, you issue another

S * IN listname WHERE SENDER CONTAINS NIH.GOV SINCE yyyy-mm-dd

Repeat until you have less than (or perhaps equal to) 100 entries.

Other SINCE formats:

The syntax is very flexible and you can specify a date and/or time in just about any of the commonly used formats:

23 Jun 1986 (self explanatory).
1986-06-23 (international date format).
1995 or just 95 selects 1 Jan 1995 for the "Since" box or 31 Dec 1995 for the "Until" box.
APR selects April of the current year, 1st or 30th depending on whether this was entered in the "Since" or "Until" box.
APRIL 95 is the same as above, but for the year 1995.
TODAY-7 (7 days ago) makes it easy to get a list of all the messages posted in the past week. You can also use YESTERDAY or TODAY for a shorter time span.
