How do I use Greater Than in a string

[devanoverstock]

I have a field called rules_tripped

It returns the results like this 

rules_tripped="5237260000001713515:Item Sku Fraud & Chargeback Percentage 0:0"

Rule ID : Rule Name : Rule Score

I want to only search for rules that have a rule score of > 800 

Is that possible to split the query and search for only rules with a rule score of > 800?

That worked perfectly, thank you!!!

Try this

| eval rules_score=mvindex(split(rules_tripped,":"),2)
| where rules_score > 800
