You'll need some attributes for that.

88 (max pipebombs increased): 8 + this stickies can be placed at once. Sco Res has this set to 6, resulting in 14 stickies at once.
78 (maxammo secondary increased): max ammo is 24 multiplied by this. Sco Res has this set to 1.5 for a total of 36.

Unfortunately, TF2Items doesn't have a setting for unlimited for either of those. Also, these attributes don't change the stickybomb mode, so they will act like stock stickybombs (i.e. all explode at once).
