The problem, as TFA points out, is that 1) the inscriptions are short, on average 5 symbols, 2) the underlying language and even the language family is unknown.
Most (all?) decipherments have relied on having an idea of the language at least. What we have here are lots of seals with a bit of text, not paragraphs with real structure to analyze, maybe not even sentences.
Since they are seals, maybe they are mostly labels identifying the owner, or maybe some transactional label. In which case you will be hard pressed to extract a language from them. You probably will need longer examples to make progress.
