The stuff Pinnacle/Score was doing right before bankruptcy was so confusing. It took a while to straighten out all those Epix inserts they put out, not just in baseball but football and hockey too. That's why the Release Notes on the insert in Pinnacle Plus tell you where the other half of the set is hiding.
Cards appear in 1998 Score Rookie & Traded (Emerald, Orange and Purple inserted 1:31 Retail packs, 1:61 Hobby packs) and 1998 Pinnacle Plus (1:240 packs). This set contains #E13-E24, while Score Rookie & Traded contains #E1-E12.
...and on the Score R&T side:
Cards appear in 1998 Score Rookie & Traded (Emerald, Orange and Purple inserted 1:31 Retail packs, 1:61 Hobby packs) and 1998 Pinnacle Plus (1:240 packs). This set contains #E1-E12, while Pinnacle Plus contains #E13-E24.
Notes like this will eventually help visitors of the site find their cards easier, and I'd love to see the more recent sets have info similar to this if possible.
