I have a package that is using a Script Task to set a package variable. If the variable doesn't get a valid value (a date) is there a command to cancel the package execution?

Try use DTS events inside Script to do that.
Dts.Events.FireError(-1, "", "SSIS - @LastRunDate_Dados>@StartDate! Correct the problem and try again!", "", 0)

Since you are in the package running already, not really a way to "cancel" the package - but you can certainly stop it. I reccomend using the OnCompletion precedent and adding a constraint. In other words, instead of Green Arrow connecting the next task, use a "blue" onCompletion arrow. You could send the flow of the package to a MsgBox or just stop processing. You could also send it to a Script Task and Error the package.
Connect the green arrow between the task that assigns the variable and the next task. Right click on the Green arrow and select Edit. This will give you the Precedence Constraint Editor - picture below.
Write an expression to evaluate the variable value. This is a powerful feature, if you need specific help please ask.
Does this help?

Setting the following property in the script code can determine if the precedent constraint (outlined above) will succeed or fail.

If (My code does what I want it to) Then
End If

If it's "Failure" then the precedent constraint will stop the package execution. Only in this case you don't need to evaluate anything in the precedent constraint. Just leave it with default value.
