Ah! I got it! Both the reason you might find +1 Tomes/Manuals and how the +5 versions could be made with a level 17 character!
So there is both a reason to make them (don't need to shell out 25,000 xp all at once, which means this can be done pre-epic for +5 Inherent bonuses ... without Calling Efreet or the like) and a reason why they might hang around for a while (if you use the +3 Manual or Tome, you will have to start over to get a +4 or +5; if the creator is interrupted for some reason - it gets stolen, the creator dies before it's finished, or the creator goes into dire financial straights and it get sold [but seriously, how many 17th level casters will have that problem?])
So you start by making a +1 Manual or Tome (Cost 1,250 gp + 5,100 XP), then you save it, and when you have more XP to spare, you upgrade it to a +2 ((2,500 gp + 10,200 XP)-(1,250 gp + 5,100 XP)=1,250 gp + 5,100 XP), and when you have more to spare, you upgrade it again to a +3 (upgrade from +2 to +3 costs 1,250 gp + 5,100 XP yet again), wash, rinse, repeat until +5.SRD said:ADDING NEW ABILITIES
A creator can add new magical abilities to a magic item with no restrictions. The cost to do this is the same as if the item was not magical. Thus, a +1 longsword can be made into a +2 vorpal longsword, with the cost to create it being equal to that of a +2 vorpal sword minus the cost of a +1 sword.
