[UK] Bradford Score V Contract

Good morning,

My place of work uses the bradord score system for absences, but how does this work alongside the employment contract which states I would have 6 weeks full sick pay and a further 6 weeks sick on half pay. Going by the bradford scoring system, 900+ points = dismissal but this would still not have exceeded the sick leave the contract states.

Fortunately I am not in this position, I just dont understand how it would work. The contract mentions nothing about the bradford scoring system, would the contract supersede the bradford score?
