Up Topic American Welding Society Services / Technical Standards & Publications / preheat temps. for A 709 grade 100

Table 3.2 specifies a restriction to the preheat of A 709 grade HPS70W does this apply to grade 100W as well?

No. This would indicate that A 709 grade 100W is not a prequalified basemetal. Meaning that a WPS would need to be qualified in accordance with clause 4.
