Actually I have never seen @if nor have I tried PlayFramework. But if is what I think it is, it seems that when you actually try to ask for letter it's already out of scope. What happens if you re-arrange the brackets as follows?
@for(col <- List.range(0,12)) {
<td>
@if(col % 2 == 0) {
@{val letter = someMap(col)
<div class="z@(letter)@(letter)s"></div>
}
}
</td>
}

The only way I got this working on Play Framework 2.8.x was with Scala's Range function:
@import scala.collection.immutable.Range
@for(col <- Range(0,12)) {
<td>
@if(col % 2 == 0) {
@{val letter = someMap(col)
<div class="z@(letter)@(letter)s"></div>
}
}
</td>
}
