I don't know if it's affordable for you, but imho decent results can only be achieved if you do segmentation yourself and then pass image fragments to Tesseract on a word-by-word basis. Problems may appear when you have words that are too short, however, as I can see, it's not your case.
Long time ago, I had started my project relying on Tess's segmentation and struggled much with it, until I came to a word-by-word approach. Finally, I even switched to the character-wise recognition which at last produces decent results. Mostly this transition was caused by specifics of input images I'm working on (photos, usually of low quality), but I think this is almost required for ideally scanned images too. There are some fruitful math ideas behind Tess's segmentation, but I think the current implementation is not mature enough to be used extensively in the production mode.
